    Could this be your system replying to a message from the .ru and .qq domains.

    Maybe these domains have spammed your server, and your server has rejected them with a bounce message ?

    Terminate the account of the offending user. Or if their account might have been compromised, perhaps force rotate their password.

    Hello @thanasis,

    There's a thread here with discussion of blocking outgoing email to a specific TLD, however generally the better approach is to address the source of the SPAM. Can you share more information about the offending account? For instance, were the emails sent using SMTP authentication or through a PHP script?

    Thank you.
