registration which is followed by approval through link in the mail. But
the system is showing the error:

"The system is currently unable to send email. Please try again later. If
this problem persists, please contact the administrator with details."

Failed to create smtp connection to 192.168.x.x

Failed to create smtp connection to 192.168.x.x

but its (system) establishing the smtp connection via telnet on port 25 to
