Excellent timing, Gilbert! I was just looking for something to add for my personal mail setup, though I've got qmail instead of sendmail.
What I did find though, might be helpful for others too. There is another program called qpsmtpd, which takes a plugin approach. This allows for multiple ways to handle the incoming message, with an included greylist plugin as one of them. It also supports DNS block lists, virus and spamassassin scans, and even the sendmail milters you mentioned.
It started out as a replacement for qmail-smtpd, but is now quite flexible, and can sit out in front of other MTAs as well. If interested, it can be found at: http://smtpd.develooper.com/
