SMTP doesn't use Encryption

Hey, My Mail Domain is Secure with Let’s Encrypt SSL.

But when I am trying to connect email via SMTP in thunderbird, Its detecting STARTTLS for Imap and None for SMTP. and I am getting this a “smtp.domain.com does not use encryption” How do I fix the issue?

Use in both cases mail.domain.com

oh yeah that’s completely on me. Thunderbird keeps changing the outgoing server to smtp.domain.com even if I put it mail.domain.com. I have no idea why

It’s still not working. I gave up thunderbird since it keeps changing stmp to stmp.domain.com

I am using another client called emclient and facing the same issue

I copied all the settings provided on the right side in hestia panel mail settings

Delete the smtp dns record and it should work fine


Deleted STMP from dns, retried, no luck

Maybe cloudflare in place?

you didn’t write correctly

try smtp.domain.com and not stmp.

this address should be present (you have to add it) in DNS records of the domain

Cloudflare doesn’t proxy mail server.

Yeah my bad. The actual server was mail.domain.com Thunderbird kept changing it automatically for some reason. So I switched to EMclient.
