> It's a shame to have to give up IDA.... V8 doesn't do username-hiding > nearly as well. I have ported the IDA kit to sendmail 8.6.12, although it does require a small patch to the source. You can pick up the IDA extensions from ftp.connect.com.au:pub/mail/sendmail.8.6.12.ida.tar.Z. The patch changes some of sendmail-8's ruleset handling and I don't believe it affects the underlying security of the program. Username hiding works fine in this version. Ben.
