Procmail

Procmail ist ein Mailfilter mit dem man z.b. Spam- oder Maillinglistenmails automatisch in ein Unterordner verschieben kann. Filterregeln können mit Horde(Ingo) erstellt werden.

Logfiles

QMail schreibt seine Daten in dem im TAI64N-Format in seine Logfiles. Das mag zwar für die Auswertung der Logfiles sehr nützlich sein, lesbar ist es nicht. 

cat /var/log/qmail/smtpd/current | tai64nlocal
