I have not had exactly that problem but I have seen persistent bad 
password dialogs when I have too many concurrent IMAP sessions open to 
an account. This is unlikely to happen with MailMate alone and a normal 
config, but if you have multiple devices and/or multiple IMAP clients 
and/or have used the MM 'hiddden' setting that can increase the 
concurrency, you can get too many connections open.

The Activity Log should show the full error message from the IMAP server 
when authentication fails, which MAY provide more details about what is 
happening in your case.

Probably because MM manages up to 3 (by default) connections 
simultaneously per account and closes them when they are not in use. 
This means MM does more logins than a client that uses only one 
persistent connection that is kept in IDLE mode most of the time.
