This type of error is handled differently in the latest beta of 
MailMate. It won't really fix it, but you shouldn't get the error 
message. Instead MailMate replaces the email with a dummy message. Hold 
down ⌥ when clicking “Check Now” in the Software Update 
preferences to try this.

Apple Mail might work because it asks for the message in a different 
way, but it's strange if it works in MailMate on another machine (if 
it's the same revision).

If you hold down ⇧ when clicking “Retry” then a log file should be 
generated on your Desktop. I'd like to see that to see exactly what the 
server reply is.

My general advice is never to do this unless I've explicitly suggested 
it. For most types of problems it won't make a difference and it'll be a 
waste of time/resources.

No, you can change the “always ignore” setting by removing the line 
with `ignoreFailedUIDs` from this file (when MailMate is not running):

	~/Library/Application 
Support/MailMate/Messages/IMAP/<account>/State.plist

If the problem then returns then we can debug it.
