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.

Note that I'm speaking about deleted emails, not purged emails. As per
the IMAP spec, purging should be done separately.

Yes, that bug has been reported many times over the years, and never
fixed.
