I've used Russell Coker's* postal in the past.

*Of bonnie++ fame.

You can also try Xstress although you will have to compile it from the source code.

From their Readme:

xstress is an SMTP Stress Testing Tool. Essentially xstress creates multiple connections to (your) mail server and sends multiple mails repeatedly over all connections.
