second domain not working

[Mario Remy Almeida]

Dear All,

How to I get a second domain working?
I already have 1 working domain with qmail-ldap

Added the 2nd domain to rcpthosts and locals files also added the user 
for the 2nd domain in LDAP database and even able to find the user with 
qmail-ldaplookup

But when I send email to the 2nd domain in the log it says to remote for 
the 2nd domain and says
