OS X Server? or OS X (client)?

Log entries please.

Please provide your postconf -n . That will show how postfix is actually configured, not how you think it is configured by providing just a few lines out of main.cf.

Mailman’s dumpdb is for Python databases. aliases.db is not a Python database.

It means dumpdb is the wrong tool for dumping aliases.db.

Show log entries and postconf -n as requested above as it looks correct at first glance. Also, check your master.cf to see if there are any overrides (-o) on your smtpd entry.
