I don't know. Google is sending everything to spam on different severs. I am using tbird client. When I set up an account I normally use mail.mydomain.com for smtp and imap. But when I do that, tbird throws an error saying certificates dont match. When I view the certificate from letsencrypt it says server.mydomain.com and not mail.mydomain.com
Can someone help me stratighten this mess out.?
Now I just tried sending from a different domain and the LE cert says common name is www.mydomain.com
Thanks.
Under your SSL Certificates, make you you have the Mail service added.
Then in your DNS:
Create MX record: mail MX 0 mail.domain.com
Then create an A record for mail 1.2.3.4
SMTP should use StartTLS, while incoming should use SSL/TLS
We currently use Thunderbird 91.1.1
