To some extent that depends on the imap mailbox format used also.
But I wouldn't recommend it. Also, it depends on the size of the
messages (or total size of the messages).  The larger they get the
more performance impact you will likely see.

I do, most of the time, have up to  2000 messages in a mailbox, all of
which tend to be small.  I don't have any real performance issues.  But
my hardware is pretty good too.

The total number (70K) doesn't matter.  It is the number per mailbox that
will matter.  (The only exception is a search across all mailboxes)

If your message per folder limits are reasonable, then none.
