Dear All,

I have 2 qmail servers, they are located in different location..

qmail server A is on IP 192.168.1.9 mail.lippogeneral.com, and it has
following email addresses below:

user1@lippogeneral.com
user2@lippogeneral.com
user3@lippogeneral.com

qmail server B is on IP 172.16.2.3 .. gatsu.lippogeneral.com

user4@lippogeneral.com
user5@lippogeneral.com

The problem is when user4@lippogeneral.com send an email to
user1@lippogeneral.com .. he get mailer-daemon@lippogeneral.com .. below:

user1@lippogeneral.com>:
Sorry, no mailbox here by that name.

I knew .. this is because there is no user1@lippogeneral.com in server B ..
my question is: how to set qmail automatically send email to server A if this condition met.. ? ..
please advise .. thanks a lot in advance

Regards
Winanjaya
