    as you know there is an option on WHM Tweak called

    "Include a list of Pop before SMTP senders in the X-PopBeforeSMTP header when relaying mail. (exim 4.34-30+ required)"

    I have selected it .

    How does it work and what does it mean "when relaying mail" ?

    I know that X-PopBeforeSMTP shows all pop3 accounts in the X-PopBeforeSMTP email header to permit to identify spammers. However I don't know exactly when it's showed !

    Suppose my cpanel mailserver is (smtp and pop)
    On my thunderbird client I have set the email account
    using the pop3 and smtp .
    When I send an email to (for example) , the headers shows
    the X-PopBeforeSMTP with all the pop3 accounts !

    Why ? Am I relaying ?

    I logged on using mail.mydomain pop3 (username info+mydomain), and I sent using mail.mydomain smtp ....
    For what reason the server is sending X-PopBeforeSMTP headers ? I am NOT relaying !

    Anyone can explain me please ?

    Thank you!

    yes , that is very annnoiding. to me its not a right option. X-PopBeforeSMTP is old techniq and this option in WHM is hilarious.
    better to put it off. there are more way to track and gun down spammer.
