Hello, Ive installed roundcube and everything seems alright but when i try to send an email, i get the following error;
SMTP Error (554): Failed to add recipient "[email protected]" (5.7.1 : Relay access denied)
I can setup the email account in outlook at it works without problem.
That error can occur if your email client (Roundcube) isn't setup to authenticate outgoing emails.
I'd recommend verifying in your config file (config/main.inc.php) that outgoing email is authenticated with the server.
Please also check your logs.
Why you are actually set webmail client for hotmail?!
