I have created and tested a Global Filter to filter outbound emails in a cPanel account. The filter works when testing using the webmail client. When sending an email via SMTP authentication and an email client such as Outlook, the filter does not apply and the email goes through.
I am guessing this is due to csf having some sort of priority for SMTP connections and overriding the rules. Can someone point me in the right direction? I would be happy to create the filter directly in CSF but I do not recall how I could do that using specific sending/email addresses.
