    Is there any way or log to tell why so many "anonymous" emails are being gererated.

    I see tons of qmail-remote threads that show anonymous@6.onlinehome-server.com as the sender.

    I do not want to allow this user to send and I want to try and track down how these are getting generated.

    thanks in advance

    To protect the server, for example, you can remove 127.0.0.1 address from white list and remove /usr/sbin/sendmail so that
    users have to send messages to remote addresses only by smtp and only with authorization and force your clients to customize
    their scripts to use SMTP authorization, but it will affect a lot of free applications (which usually send messages through
    system sendmail), for example it won't be possible to send messages to remote addresses through webmail.

    Also try to use MAPS zones, spamassassin, blacklists, rejecting emails for non-existing users, update Plesk and configure SPF technology, etc.

    Below is a modification that someone posted months back. The only downside is that you need to do this for all of the domains.

    the XXXX is a unique code that should be different for each domain

    Once that has been done each mail sent by php will have a unique per domain code in the Return-Path: using a tool such as qmHandle to view the mailqueue you can see this return-path and consequently go straight to the hosting account and disable the relevant script
