Spam filters have been turned on for the various DragonFly lists: (Taken from Matt Dillon’s post explaining this)
- Matches against certain really annoying viruses
- With a MIME Content-Type header of text/html
- With a MIME Content-Type header of multipart/alternative
- Without a working reverse DNS lookup
- Without a FQDN formatted HELO line
- With an invalid envelope sender. The spam filter does a realtime
connect back to the SMTP server associated with the envelope sender
and attempts to RCPT to it. If this fails the mail will be rejected.
