Yes but imap isn't a cache, pop is!

This is only a pre 2.0 problem, in 2.0 we have a cache which does check
for old stuff and automatically removes it.  It doesn't check often
enough though, so it can grow a fair bit first.

I think, I think you can just try the find above, making sure the only
files you remove are actually the messages and not other data.  I think
the 'uid-cache' file is stored elsewhere, which stores which messages
have been downloaded, so it should be safe.  Backup, try it, if it works
it works I guess.
