    Hello,

    we recently faced a problem with our emails when sending email to a specific email address it gets bounced back, i checked our log and below is the log report, not sure if the problem is at our end or at the other end:

    013-05-15 15:30:51 1UcZRy-0001xS-UX <= test@****** H=localhost [127.0.0.1]:57581 P=esmtpsa X=TLSv1:DHE-RSA-AES256-SHA:256 A=dovecot_login:test@******* S=772 id=20130515153050.16065fjhvzxnfjdu@******* T="hello" for satya@*******

    2013-05-15 15:34:04 1UcZRy-0001xS-UX Completed

    Seems your server can't connect to the receiving server.

    Check the MX record(s) of the domain of the email address you are sending to.

    thank for your reply.

    so that means the problems is at their end and our ip is being rejected by their server? since they are getting this error:

    Sorry. Your message could not be delivered to:

    (could not contact host after 11 attempt(s))

    which site is best to check the MX records and gives accurate results?

    Hello :)

    Access your server via SSH and check to see if you can connect to their mail server with a command such as:

    Code:
    # telnet mail.example-remote-server.com 25
    Thank you.

    https://www.dnsstuff.com makes some great tools that can be used to determine if the email MX record is the issue or if it is a connection problem. Since DNS Stuff is off server, you can tell if other servers are having a problem and not just yours.

    As CPanelMichael said, you might not be able to connect. They may have blocked your server for some reason. (likely an invalid reason). So being able to check from DNS Stuff makes it helpful to know if you or everyone is having an issue.

    The reason I like DNS Stuff is also because you can check your own settings. I find that very helpful too.
