    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 localhost.localdomain locahost

    # /etc/resolv.conf



    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]'
    Action: failed
    Status: 5.1.2
    Remote-MTA: DNS;'
    Last-Attempt-Date: Fri, 29 Jan 2010 22:58:29 +0800

    Return-Path: <[email protected]>
    Received: from (localhost.localdomain [])
    by (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]'>
    Subject: test
    Date: Fri, 29 Jan 2010 22:58:23 +0800
    Message-Id: <[email protected]>
    X-Mailer: OpenWebMail 2.53
    X-OriginatingIP: (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]' 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 ?

    Did you copy info from /etc/hosts cause you are missing a l in localhost

    # /etc/hosts localhost.localdomain locahost localhost.localdomain localhost

    Hmm I'm not sure, at my /etc/hosts i just configure localhost.localdomain localhost

    Thats all.

    any other information i have to add in hosts file ?
