The IMAP protocol does have a CAPABILITIES command, which does some of
this. If our filter will work with anything that is RFC compliant, then
we should avoid most of the problems.
Note that I've changed the ways things work in the imap filter in a
number of places in the latest check in. I finally gave in and read the
RFC right through and came up with a number of improvements.
* Getting hold of the uids in a folder is now done with
SEARCH rather than a complicated FETCH.
* Moving the flags to the copied message is done via the
APPEND, rather than as a separate STORE.
* All processing of FETCH responses is done via the
_extract_fetch_data function found at the top of the
module. This only handles RFC822, UID, FLAGS and
INTERNALDATE at the moment, but those are the only
ones we fetch. Unless I've made a typo, the regexs
are also correct according to the RFC.
* I doubt anyone is using it, but if expunge is set to
true, then this is now done with a combination of
CLOSE and EXPUNGE commands, which should be much faster.
* I've stopped using EXAMINE and only use SELECT to select
a folder. This should also speed things up.
By the way, I don't know if anyone has noticed, but the filter doesn't
currently remember whether a message was trained/classified between
sessions. I know what the problem is here and I've dumped it with Tim
<wink>, who will, no doubt, fix it when he gets a chance.
