    Notifying the sender of a message delivery failure

    From my point of view, notify the sender for spam/virus is not the good approach. It may good for true user but for spammer/phishing it something like "Hey, I saw you. Change your email and try to phish us again" haha. j/k

    Add a text on top of the message

    You need to modify the /usr/share/perl5/PMG/RuleDB/Disclaimer.pm to add the content on the top of message. Don't forget to backup before you do the replace. You can do difference check to verify the changes. p/s the file I downloaded from a website, not from me. I forgot the name of website.

    Mail Gateway Routing Solution

    Is GSuite (or O365) managed by you or not? From my understanding, from O365 we create the connector to proxmox mail gw, and from proxmox we route that email back to O365. I used that kind of architecture for our DLP solution.
