Hi All,
Our postfix server has recently started reporting bounces for emails that are
being successfully delivered. These are all for email addresses that are all
within our domain, with one server acting as a relay for multiple servers
within our organization. Also, there's no real pattern that I can see. Within
a short timeframe (10-15 minutes), similar emails from the same source to the
same users have alternately been recorded with status of sent, bounced and
sent. Postfix has been running in this fashion on this server for quite a long
time, but these false bounce reports just started appearing about a week ago.
This is postfix 2.1.1 running on SLES 9 SP4.
The bounced emails are recorded like this in the log:
Apr 14 17:22:57 tilapia postfix/smtp[19383]: 8F27A27954:
to=<hama...@imsweb.com>, relay=mailrelay.imsweb.com[204.132.58.6], delay=0,
status=bounced (host mailrelay.imsweb.com[204.132.58.6] said: 554 Format
restriction violation. Email Session ID: {4DA765B1-6-6565EC3F-FFFF} (in reply
to end of DATA command))
Any ideas?
Thanks.
Rusty
