That's a reason for not accepting mail from that host, but why would
a server refuse to deliver there?
I'd have to agree there....
Let's say you are yourdomain.com, I am mydomain.com . You send mail
to m...@mydomain.com . Your server looks up the mx for mydomain.com .
Sees that it's example.dyndns.org. Resolves example.dyndns.org, which
resolves to 1.2.3.4 . rDNS's 1.2.3.4. Sees that it has rDNS of
dynamic.ip.my.ISP . Rejects mail.
Sounds a bit far fetched for me...
