No, please show the output of `postconf -n` when describing your configuration. The contents of main.cf is less useful as it doesn't accurately describe the configuration Postfix is using. > But whenever I am trying to send an I got following mail logs: > > Nov 13 14:31:02 r1 postfix/smtp[2295]: D19DC8FE063: > to=<manoj.bura...@artificialmachines.com>, orig_to=<r...@textwand.com>, > relay=mx2.abac.com[216.55.191.203]:25, delay=35, delays=0.01/0.01/33/1.9, > dsn=4.1.8, status=deferred (host mx2.abac.com[216.55.191.203] said: 451 > 4.1.8 Domain of sender address r...@textwand.com does not resolve (in > reply to RCPT TO command)) This is quite clear. The sender address is r...@textwand.com. The remote server (mx2.abac.com) is unable to (DNS) lookup textwand.com, so it refuses to accept the mail. You have no useful DNS records for textwand.com, so this is pretty reasonable. http://www.robtex.com/dns/textwand.com.html
