[Rspamd-Users] locally generated mails have an incorrect DKIM signature.

[Franta Hanzlík]

I have small Fedora 39 mailserver where all components (Postfix MTA, 
Dovecot IMAP, RSPAMD 3.8.4, Roundcube webmail, ...) runs.
RSPAMD runs as milter in self-scan mode.

I want RSPAMD to also DKIM sign outgoing locally generated mails, so 
in Postfix I have included it (in addition to the smtpd_milters) also
in the non-smtp milter, in this way:
 
non_smtpd_milters = { unix:/var/lib/rspamd/milter.sock, connect_timeout=5s, default_action=accept }

when I send mail from mailserver somehow as:
  echo -e "Ahoj"|mail -s "posilam ahoj" franta at hanzlici.cz
then RSPAMD log on destination mailserver (Fedora 38, Postfix, RSPAMD-3.8.4)
show bad DKIM signature: R_DKIM_REJECT(1.00){mulac.cz:s=default;},...

But when I send from this same mailserver mail e.g. from webmail or is 
from it send dovecot sieve generated vacation autoreply mail, then it 
is signed well - in RSPAMD log on destination mailserver is in this 
case is detected valid DKIM signature:

   R_DKIM_ALLOW(-0.20){mulac.cz:s=default;},...

Does anyone have any idea what the problem might be?
