[MlMt] Impossible to set up multiple IMAP accounts pointing to the same IMAP server

Hi Benny,

a quick followup on this; apart from a few, mostly cosmetic, issues,
everything seems to be right; I moved the messages to a new account and
didn't lose anything in the process; I agree with you that a clear error
message would be perhaps better in this case.

While we are there, I noticed a different issue.

After the catastrophe struck, we decided to move our business email to
Google App for Work; right now I'm trying to move my emails to the new
account, but I find the process quite slow (which could be understandable)
and rather unpredictable, in the sense that, as soon as I move email to the
Google account, MailMate starts APPENDing message (as confirmed by the
Activity Viewer window), then, after some random time, it goes to the IDLE
state. The only way to make it continue appending seems to be quitting and
relaunching MailMate itself.

Have you seen something like this before?
