[MlMt] giving up - MailMate crash - won't synchronize

[Helen Holzgrafe]

Following up on my last message:

When I got the endless sync problem when moving a folder, here is the 
only thing that worked to keep going:

Force  quit Mailmate.
Restart Mailmate.
Remove completely the folder in question.
Quit Mailmate again (this is crucial for some reason).
Restart Mailmate.
Try again to move a smaller set of messages from the offending folder.

Perhaps it would be good if Mailmate could do better detecting/handling 
corrupt import files.  For me, it would have made things easier if 
Mailmate could report which message(s) seem corrupt . Then I could have 
imported the good ones with less trial and error. Maybe Mailmate could 
attempt to fix the corrupt messages and import them into some special 
folder for further inspection by the user...
