Dear Sir,

We have installed roundcube mail client on our server and it was working fine earlier.Now we can't send mail to other mail servers like gmail,yahoo,etc...

While sending mail other than our mail server we are getting error message

SMTP Error (550): Failed to add recipient "arjunaju108@gmail.com" (Please turn on SMTP Authentication in your mail client, or login to the IMAP/POP3 server before sending your message. (email.origamitechnologies.com) [192.254.190.128]:41201 is not permitted to relay through this server without authentication.)

How can we resolve this issue.Please help us to resolve this issue
