mail configuration-1.1.1

[minnu]

Hai,
I want to configure mail in such a way that mail must be send only when a bug is assigned to a user.
(ie.he should get mail when PL assigns a bug to him)
I configured as shown in attachement.Pls chk if its enough.As of now mail is going only when creating a new user.
pls see if configuration as in attachement is correct.
All other server configurations are working fine.
