Installing ARC on ALMA 8/9

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.

That thread can be found at: https://forum.centos-webpanel.com/how-to/(howto)-install-rspamd/

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. 


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

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

@Starburst

OK, I assumed that was some advanced modification you had done to enable ARC

What are the 4 lines & where do I add?

Info is at:
https://starburst.help/control-web-panel-cwp/control-web-panel-cwp-admin-tutorials/dkim-not-working-on-almalinux-9-with-cwp/

Those 4 lines go at the end of main.cf, IF they are not there already.

And while you have main.cf open, you need to add the line
UNDER (# rules restrictions), under smtpd_helo_required = yes ADD:

Code: [Select]

smtp_helo_name = $myhostname
And then restart postfix:

Code: [Select]

systemctl restart postfix
Let me know if you have any questions.
