Hi,
I too am having the same issue as others have posted in requested reverse DNS setup for a static IP on BT Infinity.
i am unable to send email to reverse.dns@btbroadbandoffice.com.
I receive a NDR as below:
Generating server: c2bthimr01.btconnect.com
reverse.dns@btbroadbandoffice.com
smtpin.btconnect.com #<smtpin.btconnect.com #5.1.1 SMTP; 550 5.7.1 Unable to relay for reverse.dns@btbroadbandoffice.com> #SMTP#
Also tried www.dnsforms.com but cant see where to request a reverse dns.
Any ideas?
