I just set up a new ISPConfig 3 Debian Lenny system in Production and Iíve been going over the error logs, tightening things up, etc. I followed the Perfect Server tutorial, the one with Courier and MyDNS.
This morning, I noticed over 30 errors like the following that accumulated over the weekend in /var/log/mail.log:
Nov 8 10:35:10 ServerID postfix/local: 40D1E12646: to=<admin1@ServerID.hostingprovider.com>, orig_to=<root@ServerID.hostingprovider.com>, relay=local, delay=0.06, delays=0.01/0.02/0/0.02, dsn=5.1.1, status=bounced (unknown user: "admin1")
Hereís the thing Ė I didnít set up a user named ďadmin1Ē on this system. Iím guessing that admin1 is a leftover from a previous installation that my hosting provider did. But thatís just a guess.
I searched the hard drive for admin1
and, besides the error logs, I found the following match:
Binary file /etc/aliases.db matches
How can I solve these errors?
Is there any way to clean up the aliases.db file given that I don't have the original?
Is there any way to know which program is sending out these emails and maybe correct the address there?
Or is there some other simpler way?
