Hi,
I've spent hours on finding the error but no success. I hope you can help:
I am running Debian with older version of mailman3 (3.3.3) and postfix (3.5).
Postfix on its own is working fine.
I set up mailman, created a site/domain (lists.yyy.com). My hostname is host.xxx.com . My IP has a RDNS entry: reverse.rrr.com .
When I send an email to my mailing list mylist@lists.yyy.com I receive an error email. The logfile says the following:
... Jun 9 00:23:38 arvak postfix/smtpd[]: connect from host.xxx.com[m.y.i.p] Jun 9 00:23:38 arvak postfix/relay/smtp[]: warning: host reverse.rrr.com[178.251.71.190]:25 greeted me with my own hostname host.xxx.com Jun 9 00:23:38 arvak postfix/relay/smtp[]: warning: host reverse.rrr.com[m.y.i.p]:25 replied to HELO/EHLO with my own hostname host.xxx.com Jun 9 00:23:38 arvak postfix/relay/smtp[]: 094895FADB: to=<mylist@lists.yyy.com>, relay=reverse.rrr.com[m.y.i.p]:25, delay=0.06, delays=0.03/0.01/0.02/0, dsn=5.4.6, status=bounced (mail for lists.yyy.com loops back to myself) Jun 9 00:23:38 arvak postfix/smtpd[114119]: disconnect from host.xxx.com[m.y.i.p] ehlo=1 quit=1 commands=2 ...
The MX record of lists.yyy.com points to reverse.rrr.com. Not sure if this is the best idea?
Can anyone give me a hint where to search for this error?
Thanks a lot in advance!
Florian.
