No, and it never was a big problem.

Perfectly stable. However, due to Postfix's design of having one file per
message instead of Exim's 2, MailScanner cannot run as fast on Postfix as
it has to do I/O on the entire message just to add a header. In
Exim/sendmail, the body of the message usually doesn't have to be written
at all, just linked into the outgoing queue, which makes it faster. In my
experience Exim can happily handle large volumes of mail, it's what I use
for all my capacity/speed tests.
