I use a trick for my sent email you could adapt to the

I use mutt as my email reader, and separate out my sent
email by month to sepperate files (one file per month).  The
filename is automatically generated using command

    "sent-mail/`hostname`-sent-mail-`date +%Y-%m`"

For a system named "myhost", this might generate:


I don't know procmail well enough to know if you can have it
execute a command automatically in such a way, but if so you
could just generate the target file (or directory) in a
similar manner.

Another method to adapt this solution would be to create a
cron job that creates a new file and changes a sym-link at
the beginning of each month, then (if you want) does
processing on last month such as compressing it into a bzip2
archive.  The problem with this method is that if you are
ever up dealing with email past midnight when that cron job
runs, you might get a few messages sorted to the wrong month
(I used to use this method and changed for this reason).

Hope this helps!
