    You can follow as per above articles,If issue not resolved you can scan your system.

    • If subject lines and recipients are displayed, examine them to determine if mails were intentionally sent from the mail client.
    • If not, isolate the computer from the network and follow best practice to determine if a currently undetected threat is operating on this computer. Checking what program is using common mail ports (performing a netstat -ao from the command line to learn what process is communicating on port 25) is often the best first step.

    DId you take the client offline and scan it to see if it is infected?

    Hi Outrageous,

    If you are sending these mass-mails intentionally, then chances are the SEP mail plug-in is just making visible an error message from the mail server.  I would check with that server to make sure it is capable fo processing the large quantity of mail.

    Please do keep this thread up-to-date with your progress!

    Hello,

    I agree with Mick, the message clearly says that is the mail server which is rejecting your emails, not SEP which just show it to you; you should contact your mail server administrator for further investigation.
