Cannot reproduce. Button disabled if fields are empty.

However, from my experience, authentication for SMTP is not strictly mandatory.

For example, for HKBN, they require no authentication as long as your IP address is a HKBN IP. From HKBN doc,

smtpo.hkbn.net is the server of SMTP server in HKBN. It is noted that it only runs if you are using HKBN’s internet connection.

So say someone self host a local Authgear instance in the intranet with a self hosted SMTP, that can work without SMTP authentication too?

Quick Googling and skimming RFC5321, the original SMTP doesn't seem to require authentication.

Suggest to add an Info tool-tip the inform user to check with their SMTP provider if they need authentication.

Thanks for pointing out authentication is not mandatory! But most of the time username and password are required, let's wait until someone complains they do not want authentication.
