[SOLVED] Disclaimer exception

[Pcom]

Hello,

I followed this guide to create a warning on top of every external mail we receive, like "this is an external mail, be careful".
It works fine and I'm satisfied, only one little problem:
some system in our infrastructure, use a cloud mail service to send mail instead of our local on premise mail server, even if mail address of these system is part of our local domain (printers, ticketing system...)
The disclaimer is applied to these mail too, which is not nice.

Is possibile to create a rule to add disclaimer to every mail EXCEPT some of them? I know the mail address to exclude, I know the public IP of the cloud mail... Maybe I can create a regex expression to exclude something? No idea how to write it.

(I know I can create a whitelist with these address and an action to only "accept", no disclaimer, with priority 99. It works but I would like to keep scanning those email, I want to just remove the disclaimer not completely whitelist them)

Any other good idea is apreciated.

Thanks

not really, but you can have some rules above the one with the disclaimer for the specific mail/ip etc. and do an 'accept' since that triggers then before the disclaimer rule it won't contain one

Yeah, I'm using a whitelist group with an "accept" and priority 99. It's not exactly what I was asking, as I wrote in the question I would like to keep scanning those mail but at the end it works and I'm satisfied.

For any other future solution I'll keep follow this thread.

Thanks.

well i'm currently working on an extension of the rule system so that one can invert matches too, with that your request should be possible, but it's not finished yet and i cannot really say when/if this will be available

i sent a first draft last week: https://lists.proxmox.com/pipermail/pmg-devel/2024-February/002663.html
