user not receiving mail

[Angela Marie Thomas]

I got email from kaih AT khms DOT westfalen DOT de  that he's not receiving
email since the outage.  If you take a look at the mailq, you can see that
there are quite a few messages of his that haven't been delivered (he is
using some MX trickiness to route his mail so look for kaih.*westfalen).

I couldn't see anything obviously wrong in the qmail logs or the rbl logs.
Can someone please take a look?

I can forward his originl mail, but I'd like to sanitize it from
potential spammers (his headers are decidedly anti-spam so I'd like
to respect that).  Is there a blessed script for sanitizing mail
that I can use or do I have to spin my own?

It looks like a problem on their end (@ replaced with -X- below):

I've done a Bcc to the person with the problem.

His messages are in the queue, and deliveries are consistently
reporting
    deferral: Connected_to_213.239.196.208_but_connection_died._(#4.4.2)/

This means that when qmail was delivering e-mail to his system, it
made a connection, but the system did not respond within the timeout
period, which is configured to be 30 seconds.  The timeout applies to
the initial greeting, and to the response to any SMTP command.

I just tried by hand, and I can confirm that his main MX responds very
slowly.  The initial greeting and MAIL FROM are fast, but the response
to the RCPT TO is very slow.  I'm sure it is consistently blowing out
the 30 second timeout used by sourceware.  I don't know why his system
responds so slowly.

The 30 second timeout is aggressive, and I could see it backing it off
to 60 seconds.  Not more than that, though.
