I’m trying to configure mailing via an external SMTP server.
The SMTP host is using Postfix and rejecting email because the HELO does not have a fully qualified hostname - it’s just showing up as “akkoma”.
reject: RCPT from unknown[redacted]: 504 5.5.2 <a
kkoma>: Helo command rejected: need fully-qualified hostname; from=<redacted@redacted> to=<redacted@redacted> proto=ESMTP helo=<akkoma>
Where is this set?
(Update: I can see that in Swoosh, one can set a “hostname” in config: Overview — gen_smtp v1.2.0 . But this isn’t exposed in the admin frontend? Have been using database config and would prefer to be consistent if possible.)
