I am facing an issue of mail notification from the servicedesk plus while creating and closing request.

As suggested in the link  http://kbase.servicedeskplusmsp.com/troubleshooting/2013/05/17/email-send-notification-failed/

i have checked the smtp server using telnet command and it's working properly.

I am stuck up with this issue, If someone have the solution please help me.

Regards,

Rajesh Patel
