[SGVLUG] E-mail archiving -- looking for ideas & techniques

[Emerson, Tom]

I'll admit I'm a bit of an e-mail packrat, which is good and bad --
good in that I can find old items not otherwise archived publicly, bad
in that some of my folders have tens of thousands of messages.  Up to
now this hasn't been a problem, but now that I'm serving it via "imap",
I'm noticing delays when retrieving messages (presumably my client and
the server are "comparing notes" on each of the headers, cached or
otherwise)  This is especially bad when checking this stuff from "offsite".

As it turns out, I only have one folder per list or otherwise "important"
classification.  I'd like to create an "archive" hierarchy (yearly/
monthly/whatever) for each of these folders so I can move the older
messages to an area I don't have to "subscribe" to from external clients.

Any recommendations on how I can or should go about this?  I know that
this can be done with procmail "recipies", but I'm not familiar enough
with procmail to create the appropriate/automated recipies, nor re-process
my existing messages to actually sort them.  Are there other "Maildir"
oriented tools to manage large volumes of mail?
