[Evolution] Workaround for "sent items corrupted" bug?

[Botond Kardos]

    Hi,
    I have the same problems as described here (with Evolution 1.2.x, 
1.4.x and 1.5.x as well): 
http://bugzilla.ximian.com/show_bug.cgi?id=28941 (IMAP copies of sent 
mail sometimes corrupted). It is considered as a bug of Exchange Server 
5.5. Don't you know of a workaround to this problem? For some reasons 
I'd like to put my sent mails into an IMAP folder, but my company won't 
upgrade Exchange Server in the near future.
    Thanks,
    Botond
