mailbackup was one of my first real adventures into Perl. I
wrote it because I am subscribed to several e-mail lists, and thus filter
mail into lots of different mailboxes. This made doing monthly backups quite
awkward and tiresome, and as mutt (my
MUA of choice) lacks a feature of PINE[1], whereby
it asks if you want to move last month's data to an appropriately named file,
I decided to create this script that could be run from a cronjob, or simply
from the command-line. It also gzip-compresses files.
As I included POD information into mailbackup, I won't bother
explaining its usage here. Just type perldoc mailbackup from a
command-line.
