Self-generated admin e-mail going nowhere

Postby mhammett » Tue Apr 16, 2019 11:11 am

I have a 6 server cluster. Two LDAP, two MTA, two mailstores. A couple weeks ago I started noticing a trend of admin@[each MTA's FQDN] sending a few hundred messages as shown by the daily mail report. I realized this morning that they weren't showing up in any of the mailboxes. I decided to check the log. It looks like each server sends a message to itself. It bounces, then disappears. What's generating what kind of e-mails and where are they supposed to be going?

Hello,

this is related to the localconfig settings :
smtp_destination
use zmlocalconfig smtp_destination to see the value.
Regards,

I didn't get a chance to look at the setting DualBoot provided, but I recently upgraded from 8.6 to 8.8.12 and something during the upgrade process fixed it... and promptly flooded my normal admin mailbox. ;-) It was disk full warnings for my two MTA servers. Logs had built up over three years and were starting to fill the disk.
