Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk Playing around with some antispam/antirelay mechanisms on my new mail server, I added in the rulesets from /etc/mail/sendmail.cf.additions as well as the check_rcpt from http://www.sendmail.org/antispam.html, but found that non-resolving MAIL FROM: domains weren't being rejected. Upon closer examination I found that a line in sendmail.cf.additions had been commented out: # R $* < @ $+ > $#error $: "451 Domain does not resolve" I was just curious as to whether this was intentional (what are the disadvantages here? can some legit mail be rejected?) or just overlooked. I also noticed that these rules were slightly different from the ones on the sendmail site, but I don't know enough about rulesets yet to be able to question anything. :-) I took out the comment and things seem to be working as expected. A bug in my MUA causes news.announce.newusers font to be sent to beneficiaries and senders of UCE/SPAM. @ mcs.net Wishes are like dishes.
