I noticed that in /var/mail there appears two files that are a bit strange: mail and uucp The contents of these files appear to be mail addressed to [email protected] and [email protected]. I don't have any users set up in ISPConfig with these names (although, of course, system-created users exist with these user id's). Why is the mail server accepting mail addressed to these "nonexistent" e-mail addresses? Can I make the server reject it, or should I just purge these files from /var/mail every once in a while? By the way, my server is set to reject mail to unknown users and I have NO catch-all addresses set up. Any insight would be appreciated! Thanks!
First, this is nothing to worry about. The mailserver accepts mail for system users by default. a) Remove the files b) Switch your server to postfix mode in /home/admispconfig/ispconfig/lib/config.inc.php
