virtual domains

[sonam]

Hi,

I am setting up virtual domains to handle mail for 
[EMAIL PROTECTED] to be delivered to [EMAIL PROTECTED]
[EMAIL PROTECTED] to be delivered to [EMAIL PROTECTED]
[EMAIL PROTECTED] to be delivered to [EMAIL PROTECTED]
and so on.

how can i set this up? i have read the documentation but must have
probably missed a step.

what i 've done till now is:
create ~/control/virtualdomains with an entry like
foo.com:check

created ~/alias/.qmail-check-user1 with an entry like
[EMAIL PROTECTED]

created ~/alias/.qmail-check-user2 with an entry like 
[EMAIL PROTECTED]

and so on. any help will be appreciated.

thank you
