Creating External Email Warning Banners

[32bitbradley]

Hi everyone, quick question.

I'm trying to get Proxmox Mail Gateway to add an HTML external email warning banner to the top of the email body if the email is not received from a whitelisted domain, like this image: https://i.postimg.cc/3x1kNngr/Capture.png

I'm struggling on 2 things, how do append HTML to the top of the email body. I have tried using Disclaimer but I can only get that to add a banner to the bottom of the email.

Secondly, how can I tell PMG to add the banner if the TO domain IS NOT in the list? So far I can only get it to match if it is in the list...

Thanks guys!

Any news on this, im looking to edit the settings of the disclaimer so it appears at the top?

i am afraid both of those things are currently not possible with pmg
a disclaimer adds a text/html part at the end
and negate the matching of 'who' objects is also not really possible at the moment

you can of couse open enhancement requests here: https://bugzilla.proxmox.com/
but i can make no promises that we will implement any of it

We have also been asked to provide an external email warning banner at the top of incoming emails.

I personally don't like these banners, but our Director is asking for this feature, and might force us to switch to an alternative email gateway

many thanks,
Jake

Hello,

I wrote a guide on how to add an external warning banner. This guide uses the disclaimer method with some modifications. Please take a look here: https://imanudin.net/2023/02/16/add...odies-in-proxmox-mail-gateway-a-simple-guide/

BR,

Hi Imanudin,

Your solution works a treat - thank you so much!

Of course if Proxmox updates /usr/share/perl5/PMG/RuleDB/Disclaimer.pm we will need to reapply the hack.

Perhaps Proxmox might consider adding this as an option to the next release?

thanks again!

I also find this feature very important and think it's a shame that it hasn't been implemented yet.
Emails are one of the highest gateways that exist.

Currently, we manipulate the subject with [EXTERN], but even that doesn't work for the employees.

Is there already a solution, which I just haven't found yet?

Thanks!

Hi Imanudin,

Thank you for sharing the guide.

But if we need outbound Disclaimer and external Disclaimer, this guide will be always at the top.
