Whoops. Sorry, Glenn. I guess a COPY to the postfix "in" queue would have
been smarter than a move for diagnostic purposes.

I've re-enabled mailscanner now and it seems so be doing it's thing
(although with all my messing around re-installing etc. I get an insecure
warning about the "file -T" command - problem for later).

I'll keep an eye on it and get back to you if it does it again. It IS
processing mail correctly at the moment, which may mean it's not a perl
update, however, this has never happened before so it would seem it COULD be
a perl update problem as well.

As for mailscanner --lint and mailscanner --debug, I'm assuming I just run
them when the problem arises? Do I need to stop (/etc/init.d/mailscanner
stop) mailscanner first or one has nothing to do with the other?

Regards,
Ed.
