Yes, and it makes it hard to debug since you cannot make a sample of the 
process when this happens.

Note that you can kill apps (including MailMate) using ⌥⌘+escape. It 
shows a list of open applications in which you can select and kill 
MailMate.

This is the same as I have (2015).

That's a possibility, but it would have to be a pretty extreme memory 
leak. I do have 1 user (maybe 2) reporting an increase in memory usage 
over time, but nothing leading to what you describe.

You can try to keep the Activity Monitor open, but note that MailMate 
does use a lot of memory and it does increase over time (due to lazy 
loading of parts of the database).

If your settings is somehow involved then it is most likely to be one of 
your smart mailboxes. You can send me the `Mailboxes.plist` file and I 
can look for anything out of the ordinary.
