Thunderbird | No emails from CFlare

Hi, I read few posts about this issue but none seems to work [1]

My domain works fine with the mail-server on my VPS. From there I’m able to send and receive emails. The DNS records looks good to me, but Thunderbird is unable to exchange emails from this domain.

I’ve MX record, SSL is Strict, and all ports are open.

When I try to add an exception for, TBird says it’s not required because the domain provides a valid certificate.

So I’m not sure what is wrong?

Many thanks,



Thank you for asking.

Seems to me the SSL certificate was recently (today) renewed and provided by Let’s Encrypt.

Regarding your DNS records, the A mail and MX record both looks good to me at first sight.

That is interesting.
