Hi root_s,

pls. check the following KB - article:

=> Unable to send an email: 554 5.7.1 Relay Access Denied​

If you still experience issues/errors/problems, try to include depending configuration files and don't forget to include MORE from your mail - logs ( serverwide AND from roundcube ) for further investigations.
