There's a pair of programs, smtp-source (an smtp/lmtp message generator)
and smtp-sink (a message dump) which might be useful.

they're written by Wietse Venema's - the author of the Postfix MTA - so
they should be pretty good.
smtp-source can use IPv4 or 6, can send many messages over one or many
transactions, can run many sessions in parallel. You can specify arbitrary
message lengths, subject, sender and recipient addresses, can generate
multiple distinct recipient addresses, random delays between messages and
various other options. It doesn't support authenticated or encrypted smtp,
afaik.

smtp-sink can accept all of the messages - I guess you need a special
router in your exim config. It supports SASL authentication, ESMTP, and
pipelining. You can configure it to reject (5xx or 4xx) or quit after any
specific SMTP command, and it has flexible logging options.
