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

The PTR is mandatory. The vast majority of SMTP senders without proper
PTR records are zombie machines spreading spam. Anyone running a real
mail
