Recently, working on amavisd-new and restarting it broke several perl modules that are required.  The results of this was that the mail server quit sending mail because it could not process mail due to the broken modules.  Here is the log file info that helped me locate the problem.

Mar 20 03:23:33 ns postfix/smtp[20284]: 992BB207DE0: to=<user@example.com>, relay=127.0.0.1[127.0.0.1]:10024, delay=1.7, delays=1.7/0/0/0.07, dsn=4.5.0, status=deferred (host 127.0.0.1[127.0.0.1] said: 451 4.5.0 Error in processing, id=19738-02, mime_decode-1 FAILED: Can’t locate object method “seek” via package “File::Temp” at /usr/lib/perl5/site_perl/5.8.8/MIME/Parser.pm line 816, <GEN13> line 65. (in reply to end of DATA command))

So once you know it is broken you can do something about it but first of all when you have a problem like this there are two external reminders.  First, my mail was not delivered.  This is a no brainer, but sometimes you just think, well….maybe things are slow.  If you have not received mail, check your logs, find the problem, verify it is all working.  Second, the pflogsumm did not arrive on schedule.  Each day I receive a log summary which provides detailed information on what has happened on the Postfix Mail Server.    Here is what was in the log summary, though it was not delivered.

Fixing the Problem:

Once you recognize perl modules are broken you need to replace them.  As root execute the CPAN shell.  and then install the two modules listed.

perl -MCPAN -e shell

cpan> install File::Temp
…
cpan> install IO::File

Once this is done restart amavisd-new and you will be set.
