It is worth to mention smtpd works absolutely fine for outgoing/incoming mail
if local machine has static IP address when:
...
table sources {1.2.3.4} equivalent to
table helonames {1.2.3.4 = smtp.domain.tld}
...
And yes, I have exactly the same action in /etc/mail/smtpd.conf
...
table sources {127.0.0.1}
table helonames {1.2.3.4 = smtp.domain.tld}
...
action "outbound" relay src <sources> helo-src <helonames>
...
It looks like a bug or misconfiguration.
