User Forwarding Mail Priority headers with Postfix/Procmail

[sofiarus]

Hello,

Is it possible to set up these headers
“X-Priority:1”
“X-MSMail-Priority:High”

for forwarded emails ?

I use Postfix with Procmail :

mailbox_command = /usr/bin/procmail -a “$EXTENSION”

Virtualmin version:	6.17

@sofiarus,

Are you looking to add these headers to “all” outbound mail?

Hello,
Yes, all forwarded mails (and why not all outbound in general).

@sofiarus,

In this case, you should look into using “header_checks”, a feature of Postfix which amongst other things lets you add headers to outbound messages.
