What happened?

In the General Settings, in the Email section, there's the "Send Test" button. If you happen to not have MAIL_REPLYTO_ADDR set in your .env file, then pressing that button doesn't do anything, but doesn't show an error. The debug log message (attached) is the only output.

The text next to the "Send Test" says:

This will attempt to send a test mail to .

(With no email address before the .)

We should show some kind of error and disable the button if that env var isn't set. I'm sure the documentation tells you to make sure to always set that variable, but sometimes, people don't follow the documentation.

What browsers are you seeing the problem on?

Safari

Can you reproduce this on the public demo?

N/A

Do you have full multiple company support enabled?

No

If you have full multiple company support enabled, do you have location scoping to company enabled?

I do not have full multiple company support enabled
