SPF bounces on migrated email account - mail forwarding broken

There appears to be a significant problem with Demon's new email
system if you rely on messages forwarded from another server (in the
case I'm looking at, emails sent to a server at an organisation we
work closely with and forwarded to the Demon account),

These forwarded messages are being bounced because the new email
system implements Sender Policy Framework. When we pointed this out
to Demon, we got the reply:

"Looking at the email headers and info you have provided the email
that is being rejected is being addressed to X...@YYY.com. This is
going through a mail filtering system emailfiltering.com and then is
being forwarded to your XXX@[DemonAccountName].com via our mail
server. The server is checking the SPF record for eu.blackberry.com,
but can't match it to the IP address used by emailfiltering.com.

We are currently working to turn off the SPF system in the next few
weeks, but the only advice I can give is to
get the forwarding changed.."

(I think the reference to eu.blackberry,com is a red herring, you get
the same bounce from any sender).

Does anyone have any clue what to do? The SPF website is just about
the most incomprehensible I've ever seen, but as far as I can tell
from this badly-written page, the only solution is for Demon to change
their SPF rules:

http://www.openspf.org/Best_Practices/Forwarding

Any help would be much appreciated.

It there any configuration option at the forwarder (i.e. at
emailfiltering.com, I presume) to enable that 'Sender Rewriting' thingy?

I don't know, since that's not in my control - it's a corporate email
server in another company with which we do business.

To be honest, I'm unclear which system does what in this (the SPF
documentation is as clear as mud). The only thing I do know for sure
is that the only thing which has changed is at the Demon end. One
might have expected Demon to (a) have warned that this might happen,
and (b) have some suggestion as to what to do about it. Having looked
a bit more, it very much seems to me as though they've failed to
follow the SPF guidelines: from the page I linked to above:

"Even a large ISP can do it. They might complain that they do not know
what forwarders their users have set up. Maybe so, but they can:
- provide a web-based configuration page to list forwarders.
- default to not reject messages that fail SPF for users who have
not configured their forwarders (but still add the "Received-SPF"
header).
- give users who have configured their forwarders the option of
rejecting messages that fail SPF."

I'm sure there will be hundreds of Demon users who get caught by this
in the migration.

I'll try emailing Demon again to see if they have any better answer
than 'we might switch off SPF in a few weeks', but I'm not optimistic.

Thanks for the response BTW!

There's no excuse for that. SPF is something Microsoft is pushing, but
it is by no means widely used yet. I don't have a tame Exchange 2010 I
can play with, but 2007 certainly doesn't bounce using SPF by default,
it just makes rude comments in the headers when SPF doesn't exist.

Why is Demon using software in which none of their staff have basic
competence? I have no official training in Exchange, but I'm damn
certain if something optional about it was upsetting my customers I'd
make it stop fairly abruptly, externally hosted or not.

But you still have the problem that all the technical staff that knew

It is widely used! A lot of spammers use valid SPF to give their spam a
bump up the reliability scale in antispam software.

Nobody sane uses an SPF failure as a unilateral reason to reject an
email, just as a slight increase in P(spam) -- and even that is now
mostly moot due to the spammers using SPF as well.

It's a useful forgery detector, but it turns out that 'is this email
forged?' is both not a very useful indicator of spam (though it *is* of
phishing) and breaks enough long-standing uses of email -- forwarding
without special client support for SPF, mailing lists -- that it is, on
the whole, no use.

> Why is Demon using software in which none of their staff have basic

If they're bouncing just on SPF failure the people running their mail
system are nincompoops with no experience in running mail systems (or,
at least, if they *have* experience it is more than five years old and
so may as well be obsolete). I appear to have garnered more knowledge
than them just by running an SMTP server for a single person and hanging
around on a couple of antispam mailing lists...

Since Demon staff no longer seem to read this newsgroup, I've raised the
issue on their web forum at http://forum.demon.net/
(Though Demon staff seem to be reading the forum less and less often as
well, and at present it's being overwhelmed by spam posts.)

As many of the posts on the forum (spam aside) seem to be telling them
that their service or explanations are rather less than adequate, I
suspect that they are doing the internet equivalent of sitting with
their fingers in their ears saying "la la la, I can't hear you".
Eventually the customers will give up and go elsewhere, thus (no pun
intended) solving the problem. This could of course lead to increased
unemployment.

This newsgroup and the forum are both a waste of time. The only way to
get through to Demon is by phone and even then it can be a fight.

I think I'm about to give in ... I had a look this evening ... just a

I didn't see any actual spam in my quick look. Can you give me an

If they've outsourced t his service then there will be a charge every
time they ask for a change and maybe even every time they ask a
question. It's also usually not a good idea to ask one question at a
time but to wait until they can put together a bundle of all questions.

A friend of mine was a telecomms consultant on the Channel tunnel and
when he joined the project asked for a telephone. Because of the above
reason the bloody tunnel was finished before he got his phone!!

That's a different lot from the batch that I saw, which had English
subjects. Their anti-spambot measure when you register is perhaps
inadequate.

Yesterday I did finally get a response on the web forum. To quote:

"Currently, SPF checking on the new platform is enabled, but based on
user feedback and our own testing based on circumstances such as yours,
it is something we're actively looking at in terms of potentially
disabling."

I'm not sure whether that's reassuring, in showing that Demon recognise
that there's a problem, or worrying, in that they don't seem to see it
as urgent enough to have disabled SPF already. Will they perhaps still
be "actively looking" at disabling it in a month or two's time?

Maybe they need to listen to this:-
http://www.grc.com/securitynow.htm
Episode 353 "DMARC eMail Security"

(Including a description of SPF etc, I'm only part way through it, but
will complete listeing later today, while driving to a customer, and
back.)

There are three forms of text transcript of the audio podcast too so
fully searchable.

of a mail client of one form or another.

As for "key benefit" #three. Only time will tell.

Somewhat belatedly responding, but it's a convenient place to add this.

The continued complaints about Demon's implementation of SPF made by
various people on their web forum seem at last to have borne fruit. It's
going to be possible for people to opt out. See posts to the forum by
the Demon staffer "Chris" for details.

Demon support have fixed my domain so that inbound SPF checking is
disabled. This is done by putting a couple of new machines
(mx5/6.demon.co.uk) in the MX list with lower priority number; these
don't do the SPF checks

Good to know that they are proficient at running a closed forum then :(

I am starting to hate the latest generation of Captcha. I can't do about
half of them and some forums I visit have defective scripting that
crashes losing all input if you get it wrong :(((

Most times I remember to put my input into the paste buffer first...

How many chicken entrails do we have to offer in sacrifice on an
electrostatic prayer mat to get this sorted out then?

If you've been migrated, then you just have to ask Demon to fix it for
you. This can probably most easily done by using the forum's PM facility
to PM Chris. Emailing New...@demon.net would probably also work.

Given that Demon can accommodate the setup described above, perhaps it would
be equally amenable to adding the customers's hostname in as the lowest
priority MX, for those customers who would prefer that.

Some credit to Demon for listening, despite their "tough, that's how it
is" mantra all summer.

Having set up alternatives (couldn't live with SPF bounces for 4 months)
I wonder if I can and should now revert to pointing all incoming at
Demon? It would reduce the number of POP3 collect sessions and probably
ease my internal routing complexity.

I am reluctant to try it out too soon because post migration one of my
important customers was getting bounce messages and grumbling. I don't
want to risk going through that loop again. Any user feedback saying if
it works or not would be reassuring.
