Hi,
I tried setting up roundcube last night for a website with multiple email users and followed the installation process, the software seemed to work fine and load correctly and even allow me to log in and recieve, but when ever I tried to send a message regardless of who to and which account i get the following message;
SMTP Error (550): Failed to set sender "name@domain.co.uk" (bosauthsmtp12: Host 00.00.000.00: No unauthenticated relaying permitted)
Any ideas how to solve this, I've looked on forums and found no working solutions.
Cheers
