Hi guys,



Recently i setting new Sendmail server and hosting 1 domain. And i got problem with sending mail and return with another domain as extention domain. For more detail this is what i setting in server :


# /etc/hosts

127.0.0.1 localhost.localdomain locahost


# /etc/resolv.conf
nameserver 165.21.83.88
nameserver 165.21.100.88


#/etc/sysconfig/network
NETWORKING=yes
NETWORKING_IPV6=yes
HOSTNAME=mail.jcmetal.com.sg


#hostname
S3Server


I test sending mail to any domain was no problem. Then suddently issue happen
when my user sending mail with wrong email address format, my user type below format in "To:" as rcpt :

<‘[email protected]’>


then email bounce back as below :

Final-Recipient: RFC822; ‘[email protected]’.inovuus.com
Action: failed
Status: 5.1.2
Remote-MTA: DNS; agf.com’.inovuus.com
Last-Attempt-Date: Fri, 29 Jan 2010 22:58:29 +0800

Return-Path: <[email protected]>
Received: from enterprisesg.com (localhost.localdomain [127.0.0.1])
by s3.inovuus.com (8.13.8/8.13.8) with ESMTP id o0TEwN5G026571
for <‘[email protected]’>; Fri, 29 Jan 2010 22:58:28 +0800
From: "test" <[email protected]>
To: <‘[email protected]’.inovuus.com>
Subject: test
Date: Fri, 29 Jan 2010 22:58:23 +0800
Message-Id: <[email protected]>
X-Mailer: OpenWebMail 2.53
X-OriginatingIP: 125.163.176.50 (test)
MIME-Version: 1.0
Content-Type: text/plain;


My issue is why email bounce back was added another extention domain which not host in my server.

‘[email protected]’.inovuus.com


Inovuus.com was not host in my server.



Btw, My domain DNS is not in my server but host in our datacenter DNS Server. So my server only run Sendmail Mailserver.

i will appriciated if any one in here can help me and give me solution, where is the setting in sendmail to fixed this issue ?



Thanks
