Default can't send/recive email

Hi, im using ISPmanager Lite 5.55.2 / CentOS 7.2

When i try to send a email with roundcube i recive msg
Code:
SMTP Error (-1): Connection to server failed
when i send a email to that mailbox i recive msg

Code:
Delivery to the following recipient failed permanently:

     webmaster@mydomain

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the server for the recipient domain 

The error that the other server returned was:
550 relay not permitted
some suggestions ?

Hi,

Do you use SMTP authorization?

550 relay not permitted error often occur then email sent without SMTP authorization.

The error "550 relay not permitted" occur then email tries to sent without smtp authentication. First of all needs to check that.

Try to send email from cli or another email client, is there the same error?
