The IMAP protocol provides *no* guarantees about consistency when two or
more clients are accessing the same mailbox simultaneously. This is not
an Evo problem. Increasing the frequency of expunges will reduce the
possibility of race conditions but not eliminate them entirely (BTW
that's probably why your filters aren't working as expected.)

In fact, the problem is that Evolution doesn't even marks the mails as
deleted on the server, and that's a *BUG*.
If you remember to put Evo offline before suspending (the small icon in
the bottom-left corner), Evo will tell the IMAP server which mails are
deleted and all is well (you can even purge or undelete the deleted
mails with an other client). The problem is that it should do that
regularly, in case of lost connexion or "surprise suspend".

Thunderbird does it and it's a life-saver.

Exactly! Thunderbird does this very well and I think it uses a "regular
expunge" approach.

You didn't read my mail. Thunderbird doesn't "expunge" anything unless
told so. It just tells the server the mails have been marked as deleted
right when they are, whereas Evo does so only before deconnection from
the server. There lies the trouble.
