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:
