Title: Reverse DNS (PTR) records
Post by: JodyStewart on March 21, 2005, 09:21:18 PM

How can one get SME 6.0.x to look for reverse DNS records of those that send email?  I would like to enable this feature for the obvious anti-spam benefits.

PTR records are already looked up, and are listed in Received headers of all mail messages which pass trough the server. But I think you are asking for something different - perhaps DNS lookup of the purported sender email address. SpamAssassin and ASSP do that, amongst other things.
