dear god, I know way too much about it now, but I'm glad I do.... my mail is sooooo fast and cool now. I'm using mbx files instead of mbox, so I have damn fast access to them and can have multiple IMAP connections open at once to the same folders, even deleting and expunging from both connections. woot. fun fun.
so if you want to reply to this entry and talk about tacos or anything, go ahead... I want to test that all my procmail filters are still working now that I had to change the delivery mechanism.
