Email Verification with Self-Hosted

It's not a bug. The first error message is caused by the wrong port for TLS SMTP, the second one – by Outlook's requirement of Oauth2. Something like resend.com will work just fine. It's pretty user-friendly too :)

I could be missing something still. My understanding is to use port 587 for TLS/STARTTLS, which produced the first error.. 465 would be used to upgrade to a TLS connection, but I have tried that as well and still, unsuccessful. You're saying for me to sign up with resend.com? That is something I can try out too, but would prefer this to just work with my outlook. Zoho is similar to resend it looks like, but I get failures with that account too
