Verification email has invalid From: header value of 'https:;'

Description:

Just installed 0.74.3 server on Fedora-29 and have created some accounts. I went to validate my email address via "Resend Verification Email" and it failed sending to localhost:25. I got tcpdump up and can see why.

I have DKIM enabled on localhost and it rejects the email due to it having a From header of

From: https:;

Invalid - so the DKIM parser rejected it. I have configured the From header to be a legitimate address under /admin/Email - and the "TEst email" button there works correctly and I get the test email - but it looks like the Validator uses a different From: header - and that's not set?

Steps to reproduce:

1. Resend Verification Email
2. get error "Error trying to send email: Message failed"
3. tcpdump shows the bad From header and the DKIM error that causes

Expected behavior:

legitimate formatted email is needed

Actual behavior:

Start with the Resend Verification Email flow and the email settings under /admin/Email, then compare its sender configuration with the working Test email path. Reproduce the failure and inspect the generated message; done means verification emails use the configured legitimate From address and are accepted by the local DKIM check.
