Unable to send email to external addresses

[pccsq1]

Hi All,

I have installed Roundcube on my server to replace Squirrel. It works fine except that I cannot seem to send emails to any external email addresses.

In other words, I can only send emails to domains hosted on my server. The error I get is:

"Failed to send email"

This is rather odd and any help with this issue will be very much appreciated.

Many Thanks ...

Kenny
