Greetings, thx.

 

Did you create the certificate as shown in the tutorial?

 

Hi, yes, I have created after the error messages, but the error persists without giving warnings about the certificates.

 

Please add mail.midominio.com to mydestination in /etc/postfix/main.cf and restart Postfix.

 

Finally I have looked this guide and it runs perfect.
