Added 2 commits to my master (and next) branch, that tries harder to
really drop a connection in that case. Let me know if it helps. You will
still get an exception when switching I guess, but it should continue
with a new connection.

commit dd02c307db3365ce64471f440aa7ddc58f5a2917

    Drop connection if it might be bad on APPEND
    
    1) Differentiate error messages between imaplib.abort and imaplib.error
    exceptions in the log.
    
    2) Drop connections in the case of imapobj.error, it also might denote a
       broken connection.

commit 3aded16ed4de691d79581f3b27d4da8dd9bc684d

    Make releaseconnection a NOOP when conn is None
    
    During cleanup we often call releaseconnection in a finally: block. But
    in cases of error, we might have dropped the connection earlier already
    and set it to "None". In this case don't fail releaseconnection() but
    make it a NOOP.
