Re: Missing mail.log files

Consider also that there are different loggers, different way to
implement logs and not a right way to do it, so it is really possible to
have non-optimal log-rotation scripts.
I don't use postfix, so I did not investigate if there are bugs.
In debian, nothing logs directly to /var/log/mail.log, everything comes in
via syslog, so only syslogd ever has the file open for writing. Log
rotation is controlled IIRC by savelog hich controls ALL rotation of all
logs for syslogd logs, so i there was a bug in that he should be missing
chunks from everything.
The (most) likely explanation is running out of disk space in /var,
followed by someone (accidentally or not) removing the logs, followed (very
distantly) by some new bug in the log rotation scripts. I haven't checked
any of my deb5 machines yet, but I've never seen this happen with deb4.
Though running out of space in /var would possibly result in missing other
logs too. I don't think it was mentioned if the log.N's are sequential or
not. Or if he has compression in use on them or not.
