Installing ARC on ALMA 8/9
« on: June 27, 2025, 03:37:50 AM »
Hi everyone,

Just wondering if anyone is brave enough to post a how to set up the new ARC authentication for email on ALMA 8/9 CWP servers. I'd love to get it sorted early on.

You can follow Netino's guide for rspamd -- it works on Alma 8 and will get you ARC headers.

Just note one formatting error in his instructions (these two were grouped together in his instructions but are separate files):

- file /etc/rspamd/local.d/worker-proxy.inc
Code: [Select]
bind_socket = "127.0.0.1:11332";
milter = yes;
timeout = 120s;
upstream "local" {
 default = yes;
 self_scan = yes;
}

- file /etc/rspamd/local.d/logging.inc
Code: [Select]
type = "file";
filename = "/var/log/rspamd/rspamd.log";
level = "error";
debug_modules = [];

I just looked at a test email from our domain name to a google account, and it has ARC headers.  :o


FOIA - I'll see your header, and raise you a Sharpie...  ;D

And I'm not using rspamd or OpenARC

Thanks all.

I think I'll have to research it further when I get some time (the WHM servers I manage all have ARC without any set up required). Was hoping for an easy fix & although Netino's guide looks great I wanted to retain SpamAssassin & CWP defaults.

@6Sense

I can understand that.

But as you can see from the screenshot above, we have ARC enabled.
Just have to add 4 lines to the bottom of main.cf
