Re: [GTALUG] lazy jail server admin forced to act

| From: D. Hugh Redelmeier via talk <talk@gtalug.org> | How to read this: | mx: | email sent by mimosa.com should only come from its servers | declared in MX DNS records More accurately, this means that mail that says it is from mimosa.com is OK if it comes from one of the SMTP servers listend in MX records. In other words, this test only marks good things. Then the "~all" says anything that isn't good is bad.
