Delivery issues

[TaylorGaffney]

I had posted a topic a week back, and still having issues with mail
delivery to a specific account outside of our exchange server.

I have users that use xx...@whatever.com at home, when they attempt to
send a message to it from our exchange server which is
xx...@yurconic.com it takes days upon days to receive and I think as of
now they arent receiving them at all. I have done everything to see
where the problem is and just simply out of answers. I was told we
are greylisted but why only to 1 company? I just need to fix this
a.s.a.p because the owner of the company uses the outside mail at home
too.

Thanks.

This doens't seem to be fixed yet.

Mail server host name in greeting WARNING: One or more of your
mailservers is claiming to be a host other than what it really is (the
SMTP greeting should be a 3-digit code, followed by a space or a dash,
then the host name). If your mailserver sends out E-mail using this
domain in its EHLO or HELO, your E-mail might get blocked by anti-spam
software. This is also a technical violation of RFC821 4.3 (and
RFC2821 4.3.1). Note that the hostname given in the SMTP greeting
should have an A record pointing back to the same server. Note that
this one test may use a cached DNS record.

barracuda.yurconic.com: <br /> 220 barracuda.yurconic.com ESMTP

Barracuda only filters incoming mail, why would that affect any
outgoing mail?

[Jamestechman]

Some SPAM filters do forward lookups on your HELO; if you do HELO I'm
barracuda.yurconic.com and that does not resolve; that domain may
think it's SPAM and can take subsequent actions such as greylisting. I
would take this of this first.

Ok I understand, so how do I fix this?

[Jamestechman]

In your Barracuda look for a setting that either has FQDN or HELO that
has barracuda.yurconic.com set and change to mail.yurconic.com. Or if
you have support give Barracuda a call to have them find the setting
location.

Domain Configuration

Default Hostname: barracuda - Used in bounce messages and reports
Default Domain: yurconic.com - Enter the domain to be used in bounce
messages. Example: mydomain.com

only place where barracude is spelled out....other than that I dont
know.

So I am guessing I should just contact Barracuda because I cannot see
anything in the configuration that is incorrect.

[Jamestechman]

Yes that would be the safest.

I was digging around my exchange system manager and I came across the
queues. I have tons of queues for some unknown places and most of te
message are postmaster, but there was a ptd.net which is the email
address we are not able to send to. How do I go about getting these
emails to be sent instead of being queued right away?
