Really, lost. It must be somewhere, but I just don't know where! :-|
I simply used fetchmail to fetch it, just as I'd do from any other machine. This time, however, the mail didn't end up in /var/mail/zbr or /var/spool/mail/zbr , as usual... and I have no idea where it might be...
And the worst thing of it all is that I don't even know if there was anything important in all that mail :-(
Any ideas, anyone? It's a Slackware machine, btw.
As well, consider replacing fetchmail+procmail(+spamassassin?) by some homegrown Mail::POP3Client+Email::Filter+Email::LocalDelivery(+Mail::SpamAssassin?) combo. The traditional combo requires one process per mail and plus a fixed overhead of several other processes per fetch, so it bogs down quite a bit when polling a heavily populated mailbox.
Besides that, locking works nicer, the syntax is non-arcane, etc etc etc.
