Mail server issue
Hello, it is recommended to check the log of the mail server, and it is recommended that you stick to the error message.
If the ssl of couldflare is a self-signed certificate, it cannot be used for the mail server. The certificate of the mail server must be verified by the ssl provider
Use couldflare to manage the domain name. The mx record of the domain name cannot enable proxy
thanks for your reply...
here's a screenshot from mail server log .. can you please tell me what to do?
..
regarding the ssl, i'm using cloudflare Client Certificate for both domain and mail server.. or should i use Let's encrypt's ssl ?
and all the records are not proxied ..

At the same time, check the postfix configuration, which can be viewed in the server status
"mail.135mailtest.com" is replaced with your domain name
Put:
smtpd_tls_chain_files=/etc/ssl/private/ssl-cert-snakeoil.key,/etc/ssl/certs/ssl-cert-snakeoil.pem
Change to:
smtpd_tls_chain_files = /www/server/panel/plugin/mail_sys/cert/135mailtest.com/privkey.pem,/www/server/panel/plugin/mail_sys/cert/135mailtest.com/fullchain.pem
Note to replace 135mailtest.com with your domain name.
Also check /www/server/panel/plugin/mail_sys/cert/135mailtest.com/ for privkey.pem and fullchain.pem files
You can use this command to check whether the correct SSL is configured
openssl s_client -connect mail.135mailtest.com:587 -starttls smtp
or
openssl s_client -connect mail.135mailtest.com:465 -starttls smtp
If the display is not OK, please re-apply for SSL
