Spam crashes Mail

I get dozens of spam emails every day (Verizon's spam detector is
useless). I have filters that send them to the trash, so I don't see
most of them, but some still get through.

Sometimes, most recently this evening, Mail will crash when trying
to download from Verizon's POP server. The crash takes place before
any of the mail reaches my filters. The solution is to go to
Verizon's web site and trash all the obvious spam. Then Mail works
as it should.

I've been trying to identify exactly which email(s) is/are the
problem, but every time I think I'm closing in on one, Mail crashes
and the suspect isn't present on the server.

Is anyone else seeing this sort of behavior? This used to happen
maybe once a month but recently it's been more like once a week.

El Capitan 10.11.5 and Mail.app 9.3 (3124).

I have one suggestion, try Mail->Preferences->Junk Mail and uncheck the box
for "enable junk mail filtering" to turn it off.

I'm not having the problem you are but noticed a couple weeks ago that
something changed with Mail and the junk filtering.

Email I get from administrative accounts (usually dozens a day) for mudane
stuff, results of cron jobs, hourly alarm reports for no reason at all
started to get marked as junk. Not all of them, maybe 75-80% of them.

After doing the futile apple suggestion stuff, clicking the "this is not
junk" and adding the email addresses into the Contacts it just didn't stop
doing it after a few days. Turning off the junk mail filtering did fix it
which is fine with me since it rarely worked before.

Then yesterday when going through email from last week (the 4th holiday)
which I didn't look at then, I noticed something else that I'm not sure how
or why it changed.

A little tough to explain but the admin email I get (the new Junk mail)
comes from 7 or 8 machines I oversee, mostly from the root accounts on them.

They all are configured the same way, the full name for root is "Super User"
with the email address of like ro...@intake5.ripco.com and
ro...@intake6.ripco.com and so forth.

Prior to the junk mail filter going berzerk, those emails used to just show
"Super User" in the column of messages you have. You would have to click and
open them to see what machine it was from, which wasn't a big deal to me.

I noticed yesterday, there is no longer any email at all from "Super User"
that all the email now is showing the email address for the full name.

The email itself hasn't changed, the From: line (viewing raw headers) still
shows the "Super User <ro...@intake5.ripco.com>" it's just that Mail.app
seems to not like the fact that "Super User" has multiple email addresses
anymore. So it's showing the ro...@intake5.ripco.com as both the full name of
the user and it's email address.

My theory anyway.

The point to make is, I haven't done anything here with Mail or OSX updates
that I'm aware about. Just seems weird the junk mail filtering problem and
this bit with the full names being replaced with email addresses started
around the same time more or less.

I dunno if apple can sneak in an update or patch without it being a download
for the Mail app but it's just not behaving as it used to. I mean I could
have a broken or corrupted file somewhere but no crashes or other odd
things, just those two things so far.

I'm convinced that the problem is spam because there have been at
least a dozen instances of this, and in every instance the problem
has been cleared by going to the server web site and deleting spam.

I will take a look at those windows the next time this happens. I've
never used them so I don't know what's in there. Note that Mail
crashes and can't be opened until the spam is deleted at the server
web site. So I can't look at those windows until after the problem
is cleared.

System Console has this to say:

"Terminating app due to uncaught exception
'NSInternalInconsistencyException', reason: 'Encoding a malformed
address (unbalanced quote or parenthesis), bad things may be about
to happen."

I doubt that will work, since the crash appears to be happening
before any emails are filtered. Presumably it's happening early,
when headers are being downloaded.

I have however taken your suggestion and turned off junk mail
filtering just in case. If it works, I won't know for several weeks
because these crashes occur at irregular intervals.

Yeah but I think the "filters" you are using and the built in junk mail
detector are two different things.

I never did find a explanation of how the internals of "junk mail" detection
work but it's possible it's doing it as the mail is streaming in, like how
Spamassassin works.

The manually configured filters might be a "part 2" kind of thing that is
acted upon afterwards.

It's just a guess, in my case it could just be a corrupted preferences file
or something that went wacky.

All the people I know both at work and at home have no such issue. So a web
search may make it seem like a lot, but my bet is most have no issue.

I disabled junk mail filtering yesterday and today Mail crashed
again. So in fact it doesn't work.

Yes, and then one of my filters forwards junk mail to the Verizon
spam detector, which is a waste of electrons because as near as I
can tell Verizon does nothing with the information that's sent to
it.

According to the system console, Mail is crashing because it's
receiving misformatted data.

Who is your email provider? Or do you run your own mail server?

"A lot" is a meaningless phrase. There ae about 100,000,000 mac users
running Mavericks or later. How many are having problems with Mail
crashing?

FTR I cannot remember the last time Mail.app crashed on any of my
machines (betas excluded).

He's using Verizon. So, you know, they are a huge bag of hurt who are
actively hostile to user's email. Why anyone would ever use them for
email service is beyond me.

Yeah, was a shot even though it was based on another problem I was having.

Ha, I wish you luck with that.

That's about a good of a error message as with windows and a "error
0xE000046 - Please contact your system administrator".

I did look at your dump and it seems like the cause is right after the
misformatted data line, specifically:

"PCH Sweepstakes??"" <ddwpaal...@hfdsgregularsjh.info>'

It's either that ^B hidden there after the word Sweepstakes or the fact the
email address starts with a double quote and ends in a single.

If you ask me the fault is 50/50 with both Apple and Verizon. The mail.app
just shouldn't crash because of that and Verizon because they should be
rejecting that message instead of processing it.

It looks like on my system those messages are rejected with:

reject=550 5.1.7 Sender address does not conform to RFC-2821 syntax

But the mail.app just should toss it and not try to parse it.

Verizon sounds like a shit provider if that's what they are doling out. I
have Verizon cellular service, but there's no way I'd bother using whatever
email account they've associated with my account. Then again I'm averse to
using most hosted email providers because I run my own mail server. I like
having my mail stored right here at home where I have full control and
nobody has access to it but me.

I have a Comcast business connection ($69/mo) and they don't care what
servers I run. Many residential connections block port 25 traffic
because so many (mostly Windows) zombie machines on residential
connections use port 25 for sending spam. Once I got my business
connection, I had to get tech support to unblock port 25 for my
connection. They did it with little hesitation, thankfully.

Well my IP address hasn't changed since I got this connection years ago.
So it's a fairly static dynamic IP address. : ) Regardless, I have my
domain always pointing to my current IP address through a dynamic DNS
hosting service (DynDNS) and local client so that even if my IP does
change, I'm covered.

I do relay my outbound messages through a provider (pobox.com) on the
mail server because Comcast's IP pool is apparently full of addresses
that have been blacklisted by Spamhaus etc, which would prevent relay in
some situations. That's probably common for most service providers
though. There's always a significant slice o the computing population
that allows their computers to be taken over by malware that runs mail
servers to send out spam. When I first set up the mail server I found
that out the hard way. Some messages would make it out, others wouldn't
due to my Comcast IP address having been blacklisted some time in the
past.

Well the correct answer is, you have to pay for it.

Can't speak for all of them but like here in Chicago, at the house, I have
both AT&T fake u-verse service (it's DSL but they don't advertise it like
that anymore) and Comcast.

The Comcast is just plain old residential service but the DSL/uverse they
make available static addresses, a /29 which gives you 5 or 6 usable
addresses (depending how you count the router) for $15 a month.

For that, the $15, you can put up whatever servers you want, web, mail, dns
or anything else that strikes your fancy. There is even a semi-secret email
address you can use for them to set up the reverse dns or asking nicely,
will even delegate it to you if you are worried about hostnames matching ip
addresses or vise versa.

Comcast generally steers you to get a business connection but the low end
pricing doesn't seem much different than mid residential. One thing I only
heard about (so might be untrue) is they offer ipv6 addressing (meaning they
hand out blocks) which would lock/fix the ip4 address of the router to
static but I'm not sure if the "no server" rule applies. Can't really
imagine why they would do that, the ipv6 block would seem useless.

Another cable company/internet provider that mostly covers the lakefront
area (called RCN) is supposed to have a similar offering to AT&T, for $8 or
$10 a month they lift the no-server rule and fix the ip4 address, for
another $8-$10 they assign a /29.

So probably most providers offer it somehow, if you want to pay but it'll
really take some digging down on their website or more likely a call to
them, provided you can get past the everyday sales drones.

I was wondering that myself, I have Verizon for cell also but never saw
anything for an email account, I figured he was on fios or whatever else
they offer. Giving away email accounts for something as transient as cell
customers seems futile.

Hey John, something I just thought of that wouldn't be over complicated to
do nor time consuming.

If you don't have one, or do (and get another one) is a gmail account.

Within the various configuration options they offer, there is one to poll
and pick up mail from another provider and stick everything in your gmail
account. I guess they figure people that use multiple email accounts would
find it easy just to use the one account to collect everything.

Why don't you set one up to make it pick up the mail from the Verizon
account, then set up yer mac to pick it up from gmail. Although for privacy
reasons I don't trust google as far as I can spit, would be interesting to
know if their system can handle the puke from Verizon and sanitize it.

If it seems to work as far as mail.app quits crashing, there would just be
some minor tweaks with the smtp servers and email address for Verizon, if
you use it to send mail out anyways.

Just a thought.

That's very cheap. Comcast charges $25/m for a single IP and I think $75
for a /29 (8 addresses, 5 usable). Those charges include no services, and
you cannot setup rdns on a single IP.

It would be nice is IPv6 actaully worked, but it simply does not for
consumers as there is still too much that breaks with it.

When I got my raspberryPi3 the setup defaults to having IPv6 on. I could
not download a single package or update until I disabled IPv6 and
rebooted the machine.

MOST providers that I've seen break off static IPs to business service.
With Comcast, this is an entirely separate company within the same
corporation. The tech who comes out to my house to fix things is not the
same tech that goes out to XFinity houses, doesn't work out of the same
location, and doesn't know those people.

It was the same with USWest/Qwest and is still the same now that they've
been bought by... CenturyLink.

Comcast (Business) is a lot more than XFinity (home). My bill for 75/15
with a single IP is close to $200 a month. A friend of mine has a
similar speed XFinity package that costs $60, iirc. He could double his
speed to 150mbps for $10 more a month. I could double my speed for more
than $100 more a month.

But, I do get same-day or next morning service. The techs are generally
competent. I do not have transfer caps (and have exceeded 1TB in a month
on multiple occasions).

The low-end Business plan only exists to have a low price point, as it
would be unsuitable for any business (3Mbps up). The $100 plan (25/10)
is much more reasonable for a small office or individual who needs
decent speed.

I'm paying $69/mo for Comcast's lowest tier business plan and I'm fine
with it. They have no restrictions regarding what services you can run.
I run my own DNS, mail, web, etc. services without issue. My IP address
is dynamic but rarely if ever changes. And when it does change, it's not
an issue for any of my services, including mail. A static IP is not
needed to run mail services.

That does sound the same but it isn't. The suggestion to hold down
the shift key (at https://support.apple.com/en-us/HT203542) doesn't
work because Mail crashes before the window even opens.

That was a good suggestion but it doesn't work, either. The first
time I tried it, one email came up and then Mail crashed, taking
Connection Doctor with it, so Connection Doctor yielded no
information. The one email that got through was harmless, and a
visit to the Verizon site showed dozens of emails to download. The
one that got through was in the middle of the pack, so there was no
way to tell which email had been the one that drashed Mail.

> My solution. Go back to Snow Leopard :) Works fine for me :)

This is becoming a daily occurrence. I have sent dozens of crash
reports to Apple, and maybe they'll fix it (there's no reason bad
data should crash the app if they simply write a little protective
code into the interface) but if they don't do it soon I'm going to
have to start using a different mail reader.


Does anyone have a recommendation for a replacement for Mail.app?

No, Comcast doesn't restrict business accounts at all, only constrains
the bandwidth.

I am surprised that you find the 3Mbps uplink usable. That slow a speed
would make things like Dropbox and Backblaze (or Crashplan) entirely
untenable for me.

If you want to RECEIVE mail it is, and unless you are routing your mail
through a real mailserver, most mailservers will not accept mail from a
dynamic address pool.

I don't store tons of shit in the cloud, and I have my own networked
services at home. It's usually 4 Mbps up and 16 Mbps down, which
isn't what I would consider slow. It's fast enough to have a couple
simultaneous video streams going, fairly constant encrypted P2P traffic,
and FPS online gaming with a fairly low ping (usually between 60-70 ms)
- along with my network services (dns, web, mail, etc). It's plenty fast
enough for my needs.

Nope, a static IP address is not required to run mail services. I send
and receive mail 24/7/365 to my domain on a dynamic IP address without
issue.

They don't care whether the IP address is dynamic or static. All they
care about is that someone allowed spam to be sent from that IP address.
And there are plenty static addresses in the blacklist databases. Since
you mention it though, it just so happens major cable companies like
Comcast are known for having pools of IP addresses that have previously
been blacklisted due to spam being sent by the previous owner, and they
have no problem handing those to new customers. : )

At any rate, as I already explained I relay my mail through my pobox.com
account because emails to one particular domain never arrived due to
blacklisting. And none of this prevents me from running my own mail
server on a dynamic IP address.

Many ISPs provide sets of dynamic IPv4 addresses to the Spamhaus, to
be entered into the PBL, stating that these assignments should never
send SMTP traffic direct to MX.

For example, <https://www.spamhaus.org/pbl/query/PBL720256>.

Such addresses will respond with 127.0.0.10, to a DNS query based on
d.c.b.a.pbl.spamhaus.org (or d.c.b.a.zen.spamhaus.org).

A response of 127.0.0.11 is a PBL entry indicating that Spamhaus
believes that the range is dynamic or provide generic rDNS responses
and should not be sending directly to Mail eXchange.

There are other DNSbls which also list what are believed to be dynamic
ranges, such as SORBS. To the best of my knowledge, only Spamhaus
offers providers the ability to opt-in to a DNSbl.

While you aren't sending direct to MX, as you're using POBox.com as a
MTA or relay, it's likely the receiving MX is misconfigured, to reject
mail based on deep header scanning and checks against DNSbls. The PBL
only makes statements about outbound traffic to port 25 on the
Internet.

I've been using them for years without problems until recently. In
recent months their spam filtering has gone to hell, and now I'm
getting these crashes.

Verizon appears to be divesting itself of all its landline
operations, so maybe they are skimping on maintenance.

A static IP may not be needed but on dynamic, it's a poor way of doing it.

On outbound mail you risk getting blocked by either anyone using one of
those black box mail solutions (Barracuda is one) or any system that uses
like Spamhaus or other realtime-blocklists.

Normally those have entire ip ranges that are assigned to known dynamic
pools blocked by default. Although not written into law, it's a general
assumption email coming from a dynamic ip address is probably spam. Block on
sight is the general war call.

With inbound mail, provided the person is using a sane dns server, it
probably works fine using no-ip or whatever those dynamic ip services are,
but that isn't always the case.

I don't know if they are still doing it but AOL was notorious for ignoring
authoritive TTL for dns records. Once they cached a record, it stayed cached
for 24 hours (86400 seconds). Usually no-ip set the TTL to a short, like 10
or 15 minutes but even if it was an hour, AOL still ignored it.

Your dynamic ip could of changed 2 or 3 times in the last 23 hours and they
still were sitting on the dns record from 24 hours ago.

Microsoft did something similar when they took over Hotmail for a while but
all of this isn't ancient history either.

My at&t router uses the at&t name servers by default and I've noticed in the
past when we change an ip address on one of the domains we manage, they
don't always update it either, sometimes for hours. For whatever reason,
I've never seen that behavior on Comcast.

What you are doing is like driving a car without auto insurance. Probably
works fine 99 out of 100 times but that one time it fails, it'll be painful.

Well from experience, maybe if you have a minute to answer, is there any
real quality-of-service (QOS) from them for that business account?

I'm assuming people who have business accounts still feed off the same wire
that are feeding the residential people? They don't run a different feed
for it, do they?

See what I don't get is, if it is the same feed, is there anything they do
that gives you priority to maintain that 25/10 speed?

Like I mentioned before, I'm in Chicago in the typical residential hood and
assuming everything comes from the drop in the alley for this block(s) there
could be anywhere from like 65 to 100 customers on that one line. Even if
it's only half that, what if everyone on it starts firing up Netflix at
7pm, are we all equal?

Their tv commercials here are saying you'll have the speed all the time that
you are paying for (for the business account), but being Comcast, it's
probably like their price guarantees that go out the window after you sign.

There has to be some kind of maximum bandwidth they can provide for a
particular area and just isn't clear if they do anything special for someone
getting the business account/feed.

I mean it's not like the old days of ordering a T1 where the phone company
rolled out a small fleet of trucks to do a point-to-point install, right?

It's been the case for me for years.

If your IP address changes that often I wouldn't recommend running *any*
server from it.

My current connection has had the same IP address since I opened the
account years ago. Most of the connections I've ever had gave me the same
IP for months and years even thought they we're dynamic. In that situation
running a mail server is feasible.

So the mail doesn't get delivered for a couple hours.

Me neither but then I don't use their DNS.

Not sure how they do it, but I do find my speed to be more consistent with
Comcast Business than I did with residential service.

There are pros and cons, of course. I hope you don't think I was
suggesting that everyone on the planet (or even anyone other than me)
should run their own mail server. If that's what you got out of what I
have said, you have apparently misunderstood me. What I have said is if
your dynamic IP address isn't changing daily or very often, you can run
mail services from it without issue. Of course a static IP address
preferable; but is it absolutely necessary especially considering the
extra expense? Nope.

I had to have at least one off-site backup, so uplink speed is very
important. Also, I backup my servers to my home machines, so when I have
to restore a server, uplink is really important.

Read the link I included. There are serious issues with receiving mail
on a dynamic address, including the very real possibility of someone
else receiving your mail.

Yes, they do. And there are RBLS that are simply lists of dynamic
address spaces. Trust me, I've been doing mail servers since 1995.

I bet it is far more than one particular domain. You just noticed one.
When our IP was mistakenly listed as dynamic we had weeks of mail
delivery issues.

Very fast on-site tech calls is a serious benefit. I have called in
the morning and had someone there that afternoon.

I have no way of knowing that, but it certainly doesn't look like I am
sharing a loop. I don't see random windows machines showing up as I used
to many years back.

Maintaining downlink speed has never been an issue for me (other than
when there were issues that needed fixing). On my 75/15 I consistently
get 8-9MB/s and sometimes over 10MB/s. Uplink is less reliable.

In areas where Google has come in, Comcast has "magically" been able to
provide Gigabit. In one case, they are offering 2 gigabit connections.
The speed constraints on Comcast are entirely artificial.

Yes, I can see how relying on that much constant bandwidth might be a
problem. My off site backups for my home devices are all stored on a
hard drive I take to the car once a month to bring off site. There's no
bandwidth penalty, and no need to transfer my data to anyone else who
may or may not take good care of it. I tend to prefer running my own
services over some random company though.

I did. I wasn't particularly impressed. It basically said what I already
know. There are dangers inherent in using an IP address that can change
for mail services, but if conditions are right, it works fine.

That can happen under very specific circumstances, but I haven't missed
any mail for years. The point is it can be done under the right
circumstances. It's not recommended to do it with an IP address that can
change, and can potentially have problems if the IP does change, but it
also can work just fine.

Of course. Did I say otherwise?

No delivery issues to speak of here for years with my dynamic IP
address. I'm sorry if that bursts your bubble, but them's the facts.

she'd be the last to find out.
