if you're looking to expoose the incoming IP addresses, this post:

  http://serverfault.com/questions/281231/help-linux-server-under-smtp-saslauthd-attack

has a response that says:

  You have to increase the LogLevel to 10 or more. Look in sendmail.mc or put
  something like define(confLOG_LEVEL',10')dnl

  This will log the IP number on auth failures.

Presumably, once they're exposed, any of the mechanims for softly
managing an IP blacklist would help.
