Hello every one.
I have installed nethserver 8 and I have configured the mail server, but I don’t have any option to configure the mail disclaimer.
Can someone help me with this?
I’m sorry but we can’t implement mail disclaimer on the server side to avoid breaking digital mail signatures. As alternative configure the disclaimer in the mail client. If you use the Webtop groupware you can look at Mailcards: WebTop groupware — NS8 documentation.
Edit: if someone wants to try, Rspamd’s developer published a custom script that adds a footer at pre-filter stage: footer.lua · GitHub. Disclaimer - I don’t known if/how it works.

Not many are fully aware of the pretty strict correct email mechanisms. e.g. ---- etc
If somebody has a pointer to the correct and strict email rules, please share the link.
Whatif?
I got the point. What I don’t understand, is that this kind of thinking takes options away. I don’t NEED digitally signed mails - I know I send postcards. And using NH7, I had a quite nice footer below each message. Why not continue this option and simply display a warning about destroyed signatures…
There was already some discussion when adding the disclaimer to NS7, the points are still true, see Nethserver-rspamd a new module - #32 by stephdl and follow-ups
- DKIM signing is required nowadays else your mails will be classified as spam
- altermime was used in NS7 to add the disclaimer and it’s even older now and still not maintained
Did you already try to add a disclaimer in rspamd by using the lua script as explained here? Maybe it’s an option?

There is very little info on both in the manual. Importance, how to implement, what to watch.
I wrote this few light years ago
