Following up on myself...

OK, so I found the bits about this being courier specific (which I highly suspected), and that makes sense. But I also found a few other people looking for similar functionality and a hint that it should be doable as a plugin. The question now is, is it done as a plugin, and if it isn't, where is the best place to find plugin development information so I can take a crack at writing one?

I am moving a courier installation over to Dovecot and I am wondering if there is a way to set Dovecot to automatically move purged items to trash (under IMAP). Additionally, is there a way to automatically delete old items from a Trash folder?
