Hi all. I'm on 3.3.0 MP1 (Build 9060) and getting the following in the Postfix logs:
-- sender non-delivery notification: CC98FD0370
-- message-id=<20130320060001.CC98FD0370@keys.FQDN>
-- to=<root@FQDN>, orig_to=<root>, relay=none, delay=0.06, delays=0.05/0.01/0/0, dsn=5.4.4, status=bounced (Host or domain name not found. Name service error for name=linemail.FQDN type=A: Host not found)
-- warning: no MX host for FQDN has a valid address record
-- from=<root@FQDN>, size=647, nrcpt=1 (queue active)
-- message-id=<20130320060001.C1410D036F@keys.FQDN>
-- uid=0 from=<root>
It almost seems like it is the default CentOS LogWatch feature trying to send to the default root account. It keeps trying to send this email (whatever it is) every 5 to 15 minutes.
Thanks,
Aaron
