mailbox rotation

[Brian Smyth]

Hello all,

I'm relatively new to mutt, I've been using it for a couple weeks and
really like it so far.

What options do I have to rotate my mailbox once it gets too large or
on a monthly basis? Mutt doesn't have a builtin function, correct? Can
anybody point me towards a script that would do this?

If this is answered in a FAQ somewhere, point me to it and shame on me
for not looking harder! :)

Thanks very much for the help,

Brian
