MAILFROM envfrom
will fail if the envelope "from" address has an invalid domain, or no MX or A record (either would be valid mail server pointers) - in which case I will reject the email outright (if they won't let me respond - then I am not interested in what they have to say). Also. IPNOTINMX ipnotinmx x x 0 -1 This will give 1 point CREDIT if the test does NOT fail. I other words, it does not punish people if the sender's IP happens to be different from the MX, but reduces the spam score if sender IS also the MX. From: [email protected] [mailto:[email protected]] On Behalf Of Michael Cummins Sent: Tuesday, October 07, 2014 1:26 PM To: [email protected] Subject: [MBF] NOMX My Alligate (up stream of Declude) adds NOMX to the header if the sender's mail from address has no MX. Does Declude have a similar test? Some spam is getting by my Declude / Message Sniffer, and I'm trying to find ways to affect it. I see Alliagte's NOMX in the header for just about all of them. If I put NOMX in a custom Declude filter to take advantage of Alligate's homework, how many false positives do you think I'd get? Does much legitimate mail come in without an MX? For those who chime in, thanks! - Michael Cummins
