## imap talks about 'unique ids' for messages, to be used for
-## cross-session identification. great---just what sup needs! except
-## it turns out the uids can be invalidated every time the
-## 'uidvalidity' value changes on the server, and 'uidvalidity' can
-## change without restriction. it can change any time you log in. it
-## can change EVERY time you log in. of course the imap spec "strongly
-## recommends" that it never change, but there's nothing to stop
-## people from just setting it to the current timestamp, and in fact
-## that's exactly what the one imap server i have at my disposal
-## does. thus the so-called uids are absolutely useless and imap
-## provides no cross-session way of uniquely identifying a
-## message. but thanks for the "strong recommendation", guys!

## and here's another thing. check out RFC2060 2.2.2 paragraph 5:
##
-## A client MUST be prepared to accept any server response at all times.
-## This includes server data that was not requested.

-## yeah. that totally makes a lot of sense. and once again, the idiocy
-## of the spec actually happens in practice. you'll request flags for
-## one message, and get it interspersed with a random bunch of flags
-## for some other messages, including a different set of flags for the
-## same message! totally ok by the imap spec. totally retarded by any
-## other metric.
