[Dovecot] Rfc: Limit the size of an email IN the mailbox
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?

should not be difficult to implement
dbmail has a setting after a feature-request from me because the "smart" Apple Mail resulted in crashing the server multiple times by a user on the LAN who draged the wrong attachment to a new message which was a some GB large video and Apple insists trying to save the draft each time the server comes back
dbmail.conf: max_message_size = 36700160

Maybe a new mail_max_msg_size setting that is used also by the upcoming submission server.
