[PLUG] Spam DoS attack?

[Rich Shepard]

  It certainly looks like I've been under a spammer DoS attempt this past
weekend. Has anyone else seen anything like this before?

  This flood started Friday and peaked Saturday; of course, Sunday's still
early. Well, I know that my postfix filters are working!
