After I couldn't really get amavis to add the DKIM signature or verify
the DKIM signature in conjunction with opendkim, I tried again with the
settings in master.cf. Adding the following entries works wonderfully:
submission inet n - y - - smtpd
-o syslog_name=postfix/s
Hello!
Here are my so far unsuccessful attempts to link opendkim with amavis in
order to add or verify the DKIM signature to mails.

Hi Matus!
I have just found out about the socket and changed it accordingly.
Spamassassin does its job, but amavis refuses the connection. I get the
following error message:
2024-12-24T09:32:42.431446-06:00 axum postfix/amavis/smtp[2894]: connect

Sorry, for the previous mail. Hit the wrong button!
Here the excerpt from mail.log:

Hi Matus,
As suggested by Wietse and you, I want to add the DKIM signature to
amavis in conjunction with OpenDKIM, but I'm not yet where I need to be
with the configuration.
I manage to get a signature added, but there are problems with the
socket. The following is configured in /etc/opendki

If your content filter makes chnages to the content then that
invalidates a DKIM signature.
Best practice therefore is to verify signatures before making content
changes, and to add signatures after making content changes.
