Re: Serving one domain on multiple servers

Hi,

qmail-ldap is designed for exactly the case that you are telling. It is 
main/basic feature of qmail-ldap.
You can choose the account's mailhost manually .
You can distribute one domains users to many server.  Did you read lwq 
ldap article http://www.lifewithqmail.org/ldap/  and  
http://www.nrg4u.com/qmail/QLDAPINSTALL
To achieve this here is the key parts:

  * install qmail-ldap on all servers & configure qmqp protocol in
    addition to smtp

  * use the same LDAP server settings (control/ldapserver,ldaplogin etc
    settings).
  * add domain.com to control/locals ,control/rcpthosts file on all servers
  * create user accounts with different mailhost values on ldap (you can
    use any ldap browser tool or phpldapadmin)
