    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 :


    then email bounce back as below :

    Final-Recipient: RFC822; ''
    Action: failed
    Status: 5.1.2
    Remote-MTA: DNS;'
    Last-Attempt-Date: Fri, 29 Jan 2010 22:58:29 +0800

    Return-Path: <>
    Received: from (localhost.localdomain [])
    by (8.13.8/8.13.8) with ESMTP id o0TEwN5G026571
    for <''>; Fri, 29 Jan 2010 22:58:28 +0800
    From: "test" <>
    To: <''>
    Subject: test
    Date: Fri, 29 Jan 2010 22:58:23 +0800
    Message-Id: <>
    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.

    '' 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 ?
