You might want to consider instituting a HELO-no-dots reject at SMTP
time on your MTA. That rejects a _ton_ of garbage here.
What are using to filter on HELO-no-dots?
I'm using milter-regex. My sample config is here:

What is your MTA if it's not sendmail? It may have a similar capability
built in.
I've looked at milter-regex, but I can't get it to build on my slackware
12 system.
That is surprising. What errors are you getting? (That's OT for SA, feel
free to contact me directly if you want and I'll see if I can help.)

Health Care _is_ a right - the government has no business keeping
you from getting it. But forcing somebody else to pay for your
health care at gunpoint (i.e. through taxation) is _not_ a right.
