This is a new “feature”. It's an attempt to change how MailMate 
handles the (surprisingly frequent) problems with some IMAP servers. 
When asked to return an email I have seen servers just replying NO, 
servers replying with BAD (claiming a non-existing syntax problem), and 
even servers simply cutting the connecting (but only for specific 
emails). Every time it requires a laborious debug process to figure out 
what's going wrong.

The new approach is to catch repeated issues with certain emails and 
then simply insert a dummy message explaining the problem and providing 
a bit of the logs.

In case MailMate was a bit too fast claiming that a message could not be 
fetched then you can force it to retry using “Message ▸ Reset...”. 
You are welcome to send me details if you think MailMate was incorrect 
in assuming it was a persistent problem. The error message does indicate 
that it might not be a server problem, but a problem with the encrypted 
connection (OpenSSL).

For the record, the old way to handle (some of) these problems were to 
tell the user about the problem and provide an option to ignore the 
involved UIDs.
