Guys, if my mail server announces itself as mail.somename.com and has a PTR that matches. I can send mail out as [EMAIL PROTECTED] or [EMAIL PROTECTED] as long as the MX record for the domain "anothername.com" reads as "mail.somename.com"
The original questions was how do I write a header rule similar to below, to identify if the announce name and PTR name do not match? header LOCAL_INVALID_PTR2 Received =~ /from \S+ \(unknown / thanks, Robert Peace he would say instead of goodbye....peace my brother. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Sent: Thursday, October 19, 2006 4:05 PM To: users@spamassassin.apache.org Subject: RE: Scoring PTR's >> >> > > *cirencester.co.uk*(*c204131.adsl.hansenet.de*[213.39.204.131]) >> >> Clearly, the PTR used here indicates a dynamic IP address.

Of course I would not like to be hosted on an adsl link but that kis a different story Wolfgang Hamann
