1. Why doesn't archivemail support bzip2 compression in addition to gzip?
-------------------------------------------------------------------------

I am quite happy to add bzip2 support to archivemail as soon as a 'bzip2'
module (similar to the gzip module) is available for python.  
[ Hint hint ;) ]


2. Can you add a switch to archive mailboxes greater than a certain size?
-------------------------------------------------------------------------

If you are using mbox format mailboxes instead, use the find(1) command instead, it is more flexible:

    find $HOME/Mail -type f ! -name '*archive*'
