Hi All,

While sending mail to a particular domain i am getting following error. Any
clue what could be the reason : -

Mar 27 14:12:15 mail postfix/smtp[27220]: 0B3418614B: to=<test1>,
relay=inflexible.cnchost.com[207.155.252.24], delay=1130, status=deferred
(host inflexible.cnchost.com[207.155.252.24] said: 450 <test1>:
Recipient address rejected: Valid DNS required on connecting IP (in reply to
RCPT TO command))

Regards,
- Puneet
