[EXTERNAL] Warning?

zaush

Is there a way to automatically add a warning banner at the top of incoming emails that are sent from outside the domain?
I’ve seen this feature in many company emails — they often display a short message above the email body such as:

[EXTERNAL - Please proceed with caution!]

Is it possible to implement something similar in Mailcow?

You can set this using a prefilter with Sieve.

Email -> Configuration -> Filter -> Prefilter.

Then put together the appropriate filter and action (e.g. comment) for external email.

CK_beats I never used Sieve before, is there a Template for that?

Unfortunately, I haven’t found a template myself yet.
Since I’m definitely not experienced in creating such scripts, I haven’t tackled such a banner yet.

zaush

CK_beats Yeah, I did not found anything myself either in that Topic :c

Try this one:
https://community.mailcow.email/d/3185-email-caution-text

Same topic!
It’s a bit older though.
But I will tackle it shortly and implement it if possible.

CK_beats I saw that before but really do not understand what is going on there. Therefore the Thread sadly is not helping in any way.
