Hello list,

My question is regarding official maillist smtp servers. I'm trying to 
subscribe on "security-notifications", but (for some reasons) our 
outgoing MX has no PTR record and mx1.freebsd.org rejects my message:


 >Reporting-MTA: dns; xxx
 >Arrival-Date: Mon, 16 Aug 2010 17:18:39 +0400 (MSD)
 >
 >Final-Recipient: RFC822; 
freebsd-security-notifications->request@freebsd.org
 >Action: delayed
 >Status: 4.7.1
 >Remote-MTA: DNS; mx1.freebsd.org
 >Diagnostic-Code: SMTP; 450 4.7.1 Client host rejected: cannot find 
your hostname, [x.x.x.x]
 >Last-Attempt-Date: Mon, 16 Aug 2010 21:24:36 +0400 (MSD)


I have the SPF record set up for our domain which designates our 
external IP as a valid sender address for the domain, but I still get 
rejected.

So, the question is: do the freebsd.org maillist servers follow SPF 
records or PTR record is mandatory?


TIA.
