I'm curious why we have such different results, unless your greet pause
is much longer than our 4 seconds.
We get spam from sender addresses @mac.com-- 217 yesterday-- but they
don't actually come from mac.com servers. Mail from smtpout.mac.com
does not hit the greetpause.

You mean what the content is? Presumably it's helo/ehlo or even mail.
If we cared, we would modify sendmail to log what it was.
