URGENT - I can't receive emails from domains external to my domain configured in Cyberpanel

Dear All,

After trying to configure spamassassin unsuccessfully, I am no longer able to receive emails from domains external to my domain.

My SMTP service is also not automatically uploading when I restarted my server, I have to upload it manually.

Could someone help me, my clients want to kill me kkkkk

Regards,

Marcelo

My /etc/postfix/main.cf

[root@osait postfix]# cat main.cf

Global Postfix configuration file. This file lists only a subset

of all parameters. For the syntax, and for a complete parameter

list, see the postconf(5) manual page (command: “man 5 postconf”).

For common configuration examples, see BASIC_CONFIGURATION_README

and STANDARD_CONFIGURATION_README. To find these documents, use

the command “postconf html_directory readme_directory”, or go to

http://www.postfix.org/.

For best results, change no more than 2-3 parameters at a time,

and test if Postfix still works after every change.
