Steve's blog

Russell asks about the interaction between blocking and callouts. If people have configured their mail server to block connections completely using blacklist data, then they're quite simply asking to not get mail. The traditional way to implement these checks is to allow connections, MAIL FROM and RCPT TO. Drop connections at the DATA stage. Normal callout connections will never get that far.

Aside: I'd have simply added this as a comment on your blog, but I'd need to set up a blogger.com account (which is a pain) and they currently don't seem to be allowing any of the 20-ish account names I just tried, including random alphanumerics (worse).
