Description Janek Bevendorff 2016-10-13 00:32:10 UTC

The SMTP configuration dialog suggests port 25 as default. This wrong. Port 25 is supposed to be the relay port, not the submission port. The correct port is 587. Many SMTP servers also accept mail submissions via port 25, but only for compatibility reasons. Some servers even block port 25 completely.

Reproducible: Always

Here it's 467 for my two smtp.
We need to define a default port and after that you can check settings.
So for me it's not a bug.
We can't know which port to using.

Regards

467 ist for TLS, but kind of obsolete. The standard port is 587 (usually
with STARTTLS) which every server should use these days. But 25 ist
definitely wrong, so I strongly disagree that this is a WONTFIX.
