Problem after adding a new database

[Naveen]

I added a new new database to my existing gnats installation (i.e. 3.1.x)
I had a earliar database called gnats-db and now I created a new called mp-db

When ever I create a problem report for my new database it goes into the 
previous database .
I checked my aliases file.I have aliases defined for both.

I am using it for first time .I  saw the flow chart ,according to that when 
you create a problem it sends a mail
to the database-
1 How does it figure from the database name the mail address?

I am using gnatsweb to send a mail  Does gnatsweb need to know the mail 
address.
When I log in to gnatsweb it shows me the new fields for the database.But 
when I submit it goes to
previous database with catgory as pending.
It does that may be becoz the mail is send to bugs which is default address

How do I send mail to mp-db.DO I need to setup an account.
How does this thing works?

Man I am totally confused

Can somebody please help me

Thanx
