Re: can not send/receive email from some domains

Please comment out "smtp_tls_security_level =" in /etc/postfix/main.cf, reload/restart postfix service and try again.

Re: can not send/receive email from some domains

*) Does it work if you set 'smtp_tls_security_level=none' in /etc/postfix/main.cf?
*) Seems sender server is trying to connect over TLS for secure connection, with 'smtp_tls_security_level=none', all sender servers should try without TLS instead.
