can someone help me upgrade sendmail -- self-followup

I'm running sendmail 8.8.5 and apparently, according to http://maps.vix.com/tsi/dnload/sm8-antirelay.txt, I may not need to upgrade to stop some dang spammers. I could just add F{LocalIP} /etc/LocalIP into sendmail.cf's local info section, but I'm worried about this ruleset code... Scheck_rcpt

can someone help me upgrade sendmail

seriously appreciate some help. :) TIA, Adam Nelson [EMAIL PROTECTED] P.S. Feel free to email me directly, so as not to overtax the group recipients.
