I have setup a mail server on CentOS 5
sendmail-8.13 I'm able to sent and receive mails from yahoo and gmail. I've another microsoft exchange server on the same network. Mails sent from that server to my mail server gets bounced. I got this error in /var/log/mail *May 30 22:11:24 myhostname sendmail[31981]: n4UGfO5L031981: ruleset=check_rcpt, arg1=<[email protected]>, relay= mx1.exchangeserver.com[public IP of exchange server] (may be forged), reject=550 5.7.1 <[email protected]>... Relaying denied. IP name possibly forged [public IP of exchange server] May 30 22:11:24 myhostname sendmail[31981]: n4UGfO5L031981: from=<usern...@exchangeserver>, size=0, class=0, nrcpts=0, proto=SMTP, daemon=MTA, relay=mx1.exchangeserver.com [public IP of exchange server] (may be forged)* As the exchange server is in my network if you do a lookup for the domain name of that server you will get the local IP only. So i changed the entry of my /etc/hosts file and added <PUBLIC IP> <exchangeserver.com> Now still the mails bounces but a different error *May 30 22:42:10 myhostname sendmail[32645]: n4UHCASl032645: ruleset=check_rcpt, arg1=<[email protected]>, relay=mail.exchangeserverom [public IP of exchange server], reject=550 5.7.1 <[email protected]>...
