Stuck incoming external message to Scalix

[lowey71]

Hi All,

Appear to have an issue with a external email that 'sendmai' on scalix is unable to deliver.

#mailq

/var/spool/mqueue (1 request)
-----Q-ID----- --Size-- -----Q-Time----- ------------Sender/Recipient-----------
m0LC49DB001832 379115 Mon Jan 21 22:04 <PERSON@EXTERNAL.COM>
(timeout writing message to scalix.XXXXX.com: Resource tem)
<INTERNAL@OURDOMAIN.COM>

#tail -50 /var/log/maillog | grep m0LC49DB001832

Jan 22 08:00:19 scalix sendmail[8460]: m0LC49DB001832: SYSERR(root): timeout writing message to scalix.XXXX.com: Resource temporarily unavailable
Jan 22 08:00:19 scalix sendmail[8460]: m0LC49DB001832: smtpquit: mailer scalix_mime exited with exit value 1
Jan 22 08:00:19 scalix sendmail[8460]: m0LC49DB001832: to=<INTERNAL@OURDOMAIN.COM>, delay=09:56:10, xdelay=00:05:00, mailer=scalix_mime, pri=1491045, relay=scalix, dsn=4.0.0, stat=Deferred

Server is running 11.3 release. We are not aware of any other emails that are having this issue as we Nagios checking the sendmail queue size.

Am able to extract mime components of this email with 'munpack'.

Assume there is some issue with the particular sender and their email with our Scalix system. If there any further way I can isolate the issue further, and it particular get it resolved!

We have a very similar problem here. Running on Ubuntu 6.06 LTS.
All else is fine and installed. Somehow, the chain:

Client -- SMTP --> Scalix SMTPD --> Scalix Incoming Internet GW --> Scalix Service Router --> Scalix Outgoing Internet GW --> sendmail -- SMTP --> Internet recipient

as described in this post: viewtopic.php?t=2243

seems to break.

The mailq and corresponding log entry show the following.

Also, omshowlog reveals:

In this case your problem is not the SMTP Relay, but the Internet Mail Gateway that's not accepting mail properly. If you are passing all mail via sendmail (using SMTP_FILTER) the chain gets modified a little, passing out from the SMTP Relay through sendmail, then back in via the Internet Mail Gateway and back to the Service Router. You need to check the Scalix logs for the Internet Mail Gateway, as well as the fatal log file to see if there's anything logged there.

But if the gateway fails it's likely due to a bug in it, I would suggest you run this one via Scalix Support so they can properly escalate it.
