@lesupremo we are still waiting for your ticket
In difference from the original OP I manage the DNS from cloudflare and not from Cyber Panel
For me also journalctl -f | grep opendkim didn’t report anything after sending mail from snappymail.
But in my case the output of journalctl -f | grep postfix didn’t report any warning about opendkim milter refused.
I don’t see any warning either, kindly show your postfix main conf.

Global Postfix configuration file. This file lists only a subset
of all parameters. For the syntax, and for a complete parameter
list, see the postconf(5) manual page (command: “man 5 postconf”).
For common configuration examples, see BASIC_CONFIGURATION_README
and STANDARD_CONFIGURATION_README. To find these documents, use
the command “postconf html_directory readme_directory”, or go to
http://www.postfix.org/.
For best results, change no more than 2-3 parameters at a time,
and test if Postfix still works after every change.

What if you remove last two lines restart postfix and try?
Not yet. Still searching for a solution
You both can reach our to our support, let see what is the problem.
@usmannasir , @lesupremo after removing both lines as below the email is successfully signed with DKIM!
But what is causing that? Why it is working OK when removing below lines?
#smtpd_milters=inet:127.0.0.1:11332
#non_smtpd_milters=inet:127.0.0.1:11332
Congrats. What is your server setup: Ubuntu/Almalinux? What version?
My server is Ubuntu 22.04.3 LTS. Anyway i don’t think that this is the right way to solve that but for the moment as a workaround is OK. Waiting from @usmannasir to see how we can deal with that issue without removing MILTER.
I’m surprised Ubuntu 22.04 even works for you. I always have to first install Inetd before Cyberpanel if I really want my emails to work. Because of these hassles, I settled with Almalinux. It’s annoying I’m now facing DKIM problems after all.
I have been using ubuntu always. Not only with Cyber Panel but also webmin/virtualmin, directadmin etc. I am very happy with Ubuntu and for me has been much stable always.
Alright. 
I think RSPAMD is causing problem with DKIM. I will create an internal task for myself to debug this.
Right now working on another issue, meanwhile if you find anything, do share.

I found the solution to RSPAMD problem, first disable dkim skining in rspamd
nano /etc/rspamd/local.d/dkim_signing.conf
add following in this file
enabled = false;
then run following on cli
systemctl restart rspamd.service
Then open your postfix conf
nano /etc/postfix/main.cf
You will see something like at the very end of your postfix conf.
smtpd_milters = inet:127.0.0.1:8891
non_smtpd_milters = $smtpd_milters
milter_default_action = accept
tls_server_sni_maps = hash:/etc/postfix/vmail_ssl.map
smtpd_milters = inet:127.0.0.1:11332
non_smtpd_milters = inet:127.0.0.1:11332
Convert it to
non_smtpd_milters = inet:127.0.0.1:8891, inet:127.0.0.1:11332
milter_default_action = accept
Then restart postfix
systemctl restart postfix
Basically you should only have one instance of smtpd_milters and non_smtpd_milters. You can combine them into a single entry as I’ve done above.
Note: I will resolve this at code-level with next release.

For your server the actual problem is not diagnosed yet.
ouch!
Okay
