I really should use this blog for keeping track of things a bit more.

Here’s one that has helped a few times for me.

Not long now..

As far as I know, there is no easy way to get exim to reprocess the emails stored in the mbox file located in /var/spool/mail/username. You can copy and paste individual emails into “exim -t” however.

Searching around with Google I came across a PerlMonks post about splitting the mbox file into individual files, exactly what I wanted!

perl -ne 'if(/^From /){open F,">msg".++$m}print F' mbox

Simply replace ‘mbox’ with the name of mbox file (in this case, “jason”), and you end up with a whole heap of “msgx” and “msgxx” files in the same directory.

Since I’m lazy, I just passed each file manually as there was only about 20 emails. You could easily whip up your own script (maybe modify the above perl script!) to pass them in “automagically”.

jason@server:~/temp$ perl -ne 'if(/^From /){open F,">msg".++$m}print F' jason
