    Good day,
    I would like to protect/restrict one of our email (distribution list) addresses from receiving emails from external domain senders.
    I have been searching the forum and came across this post :
    I don't quite follow the instructions suggested on the post.
    I have also had a look at the postfix RESTRICTION_CLASS_README page. Tried out the solutions proposed on the postfix site, but I was not successful with the attempt.
    Any suggestions on how to go about achieving this on ISPConfig 3?

    Thank you in advance for your assistance.
