I could not ever get emails to go to roundcube or any of the other plugin emails systems so I wiped out centos and now have ubuntu but problem still exist. However, now I can give you an exact error I get when sending an email to my web1 users firstname.lastname@example.org
and here it is:
-Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <email@example.com>: Relay access denied (state 14).-
Any idea on this? relay access denied??? I can send emails from roundcube. Not sure what is going on....
