Correct :)

I'm pretty sure that's close to the record. I usually tell people that MailMate can only handle a few hundred thousand if they ask.

I might regret this if there turns out to be unintended side effects, but you could possibly delete some of the database index files such as those for the “received” header. Some are more important than others for the internal workings of MailMate while others are only needed if searched explicitly.
