I verified everything once again and here are the steps which I followed to do so :-
1. I opened
http://support.eukhost.com in my browser.
2. I clicked on register option to make a new account on the helpdesk.
3. I filled up my email address and clicked on send confirmation
4. I opened my yahoo mailbox to see the confirmation link
5. I clicked on the confirmation URL which took me to the helpdesk once again to fillup remaining information
6. I filledup remaining information
7. clicked on continue
8. Clicked on 'open a new ticket'
9. submitted new ticket with a test message
10. replied to the test message from cerberus
11. clicked on 'My Ticket History' from the
helpdesk
12. replied to the ticket once from my yahoo mailbox and once from the
support help desk
13. answered both the message from cerberus.
I have followed this steps and the initial ticket creation notification came for the first time and not after that. I could see my 4 replies as separate emails from my yahoo account and inside a single frame on the
support help desk
