Hi, I'm a new member of howtoforge. Thank you in advance. My problem is as below. Recently, I moved 3 dedicated servers (CentOS 5.3) from hosting company A to B. After moving, outbound email is not working. Application is using only outbound email so, I didn't configure sendmail. The sendmail service was started and outbound email worked fine. So, I didn't change any of mail related configuration files and just started sendmail but, not working in new hosting company. /var/log/maillog ( any of email is not delivered. ) Aug 6 10:05:21 edu sendmail[2540]: n76H5KvU002540: from=root, size=417, class=0, nrcpts=1, msgid=<[email protected] testcom.com>, [email protected] Aug 6 10:05:21 edu sendmail[2541]: n76H5LYL002541: from=<[email protected]***com.com>, size=691, class=0, nrcpts=1, msgid=<200908061705.n [email protected]***com.com>, proto=ESMTP, daemon=MTA, relay=localhost.localdomain [127.0.0.1] Aug 6 10:05:21 edu sendmail[2540]: n76H5KvU002540: [email protected], ctladdr=root (0/0), delay=00:00:01, xdelay=00:00:00, mail er=relay, pri=30417, relay=[127.0.0.1] [127.0.0.1], dsn=2.0.0, stat=Sent (n76H5LYL002541 Message accepted for delivery) Aug 6 10:05:23 edu sendmail[2543]: n76H5LYL002541: to=<[email protected]****teq.com>, ctladdr=<[email protected]***com.com> (0/0), delay=00:00:02, x delay=00:00:02, mailer=esmtp, pri=120691, relay=aspmx.l.google.com.

Does it any matter with hosting company's environment for sending out email?
