Currently we're in the process of migrating Dovecot mailboxes to Exchange.
This is all working very well, except for the occasional user, who used his/her Drafts folder as a file storage: They started writing an email containing lots of image attachments (and thus exceeding our maximum_message_size by far). So the mail never gets sent, but stays in the Drafts folder.
Once I try moving that mail to exchange, it won't accept the message since it's too big. I think it would be interesting to have a limit on the total size of an IMAP object, just like in SMTP.
Thought?
