==== REQUIRED BASIC INFO OF YOUR IREDMAIL SERVER ====

- Deployed with iRedMail Easy or the downloadable installer?
- Linux/BSD distribution name and version: Ubuntu 22.04.3 LTS installer
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MySQL
- Web server (Apache or Nginx): Nginx

- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.
====
Settings enabled. but no signature.

$enable_dkim_verification = 1;
$enable_dkim_signing = 1;
dkim_key('fguztlt.ru', 'dkim', '/var/lib/dkim/mydomen.pem');
@dkim_signature_options_bysender_maps = ({
    # 'd' defaults to a domain of an author/sender address,
    # 's' defaults to whatever selector is offered by a matching key
    # Per-domain dkim key
    #"domain.com"  => { d => "domain.com", a => 'rsa-sha256', ttl => 10*24*3600 },

    # catch-all (one dkim key for all domains)
    '.' => {d => 'mydomen',
            a => 'rsa-sha256',
            c => 'relaxed/simple',
            ttl => 30*24*3600 },
});

I registered everything in the DNS. There are no errors.

I have these settings

main.cf
    smtpd_sasl_auth_enable = yes
    smtpd_sasl_security_options = noanonymous
    #smtpd_tls_auth_only = yes

dovecot.conf
    ssl = yes
    disable_plaintext_auth = no

client setup
outgoing port 25
connection: normal
incoming 143
connection: normal

iRedMail doesn't use this global parameter.
We set it in different policy banks instead:

$policy_bank{'MYNETS'} = {
    ...
    enable_dkim_signing => 1,
};

$policy_bank{'ORIGINATING'} = {
    ...
    enable_dkim_signing => 1,
};

$policy_bank{'MLMMJ'} = {
    ...
    enable_dkim_signing => 1,
}

Re: DKIM, does not sign letters

I'm confused, if all settings are same, outbound emails should be signed. There must be something wrong in other part(s).

- Do you enable SMTP authentication to send email in your MUA?
- Please show us output of commands below:

postconf -M | grep '10026'

Re: DKIM, does not sign letters

you need to use STARTTLS:

587 (Submission port for smtp with STARTTLS)
143 (Imap port with STARTTLS)
