Hello,

I've thousands log entries like the one below in /var/log/maillog. Async bounce managment does not work anymore.

sendmail[20390]: u12FJHbN020390: from=<j.doe@somemailserver.xx>, size=77120, class=0, nrcpts=1, msgid=<00dd01d15d37$b6c6f2c0$2454d840$@xxx.xx>, proto=ESMTP, daemon=MTA, relay=smtp.somemailserver.xx [xx.xx.xx.xx]
sendmail[20390]: u12FJHbN020390: Milter: data, reject=451 4.3.2 Please try again later
sendmail[20390]: u12FJHbN020390: to=<news@list.openemmsystem.com>, delay=00:00:00, pri=107120, stat=Please try again later

System: Centos 5.8
Openemm version: 2015 R2

How can I toubleshoot the issue?

I've alredy checked all other logs but did not find any abnormalities.

I hope somebody can help me with this issue.
Phil

Update:
It seams that I had a wrong libmilter installed.
After yum install sendmail-devel the error message changed to:

sendmail[3232]: u16Crsbj003232: Milter (bav): error connecting to filter: Connection refused by /home/openemm/var/run/bav.sock
sendmail[3232]: u16Crsbj003232: Milter (bav): to error state
sendmail[3232]: u16Crsbj003232: Milter: initialization failed, temp failing commands

Finally I've migrated to CentOS 7 and bounce managment works now.
