    Hello everyone.

    A few days ago I'm watching it on my server is generating a lot of mail queue.

    All emails that appear on tail, have this format.

    72FBB2A81A60 Wed Dec 17 4401 7:16:26 MAILER-DAEMON
    (delivery temporarily suspended: connect to []: 25: Connection refused)
    [email protected]

    I have currently no account registered with that name, and what I find most strange is that the sender is mailer-daemon.

    That may be happening?
    And most importantly, as I can fix ??

    I hope your help.

    Thank you very much to all

    It seems your server is sending spam and has been blocked by the remote server. You can check if your IP is blacklisted here . Also check from which ID the mail was sent, MAILER-DAEMON is not the sender, it has returened the failure message.
    if you're using postfix you can check the contents using the command postcat -q ID where ID is the one in first column of the mail logs.
