Trend Micro spam filtering
25 Feb 2005A client contacted me a few days ago about a message sent by a mailing list script I’d written being falsely tagged as spam by their Trend Micro filtering system. They wanted me to change a few things in the mailing list output to see if it made a difference, but I’m trying to track down exactly WHAT the messages are scoring points on and WHY, rather than changing things in an ad-hoc fashion in the hope of hitting something.
Trouble is, there’s close to no documentation on Trend Micro’s free desktop filtering for Outlook, and all I can gleam from the mail headers is this obscure line:
X-tis-spam: score=7.80000 (90,112102,110534,112020)
Great, hey? Has anyone had any luck/experience with filtering before? I don’t even know if it’s what’s caused that line to be added to the headers — it could be any one of the three other mail servers the message passed through before it got to his inbox!
