Dear all,

I tried to configure my mail server to use DKIM to sign outgoing mails on my 
Debian 11 with Postfix 3.5.25 and OpenDKIM 2.11.0.

Seems that Postfix is not calling the milter.

My main.cf configuration related to the milters:

## To use rspamd and DKIM
smtpd_milters = inet:127.0.0.1:8891, inet:127.0.0.1:11332
non_smtpd_milters = inet:127.0.0.1:8891, inet:127.0.0.1:11332
milter_mail_macros = i {mail_addr} {client_addr} {client_name} {auth_authen}
milter_default_action = accept
milter_protocol = 6

The OpenDKIM seems configured well:

# opendkim-testkey -d cerm.unifi.it -s default -vvv
opendkim-testkey: using default configfile /etc/opendkim.conf
opendkim-testkey: key loaded from 
/etc/opendkim/keys/cerm.unifi.it/default.private
opendkim-testkey: checking key 'default._domainkey.cerm.unifi.it'
opendkim-testkey: key not secure
opendkim-testkey: key OK

In the opendkim.conf I had set:

Socket                  inet:[email protected]

and it is running:

# ss -lnpt | grep 8891
LISTEN 0      4096       127.0.0.1:8891       0.0.0.0:* 
users:(("opendkim",pid=2382553,fd=3)) 

Using "journalctl -u opendkim -f" to check what happens when I try to send an 
email, nothing appears. I
see only DKIM verifications

I addedd
debug_peer_level = 3
debug_peer_list = 127.0.0.1

to main.cf to check for connections problem, but nothing appears.

In the master.cf there aren't milter options that could prevent the call to 
opendkim.

Where can I investigate?

Thanks in advance
