= What log files (logs) does Mailman write? =
In a source install, Mailman's log files are in /usr/local/mailman/logs/ or in logs/ in the 'var_prefix' directory.

Some packages put them in /var/log/mailman/.

The logs Mailman writes are:

 bounce:: information related to automated bounce processing
 error:: information and tracebacks from unanticipated exceptions
 and other error info.
 fromusenet:: information about posts gated from USENET via the
 mail-news gateway
 locks:: information about lockfile anomalies
 mischief:: information about unpermitted actions such as login
 failures for lists with private rosters as these can be attempts
 to fish for list membership.
 post:: information about delivered posts
 qrunner:: qrunner start/stop and other status messages
 smtp:: all Mailman's outgoing smtp sessions
 smtp-failure:: failed outgoing smtp transactions
 subscribe:: information about (un)subscriptions and address changes
 vette:: information about things held for moderator approval and
 other similar events.
