Thanks Ismail,

let me see if i understood correctly!

For each domain, i set one single MX pointing to my domain.
Then add the mx record in my domain context for each of the mail server.

It will be one mx record pointing to my domain's mx record and n ( the
number of mail server) in my domain dns for each mail server, i.e. :

1k domain records + 5 mail servers record.

Right ?

You do not have to setup 5 mx.  If you distribute users on qmail backends via \

Do you have any antispam gateway in front of the mail servers? If you have,some \
antispam gateway solutions have a feature to lookup<br> mailhost entry on LDAP and \
directly forward email to correct mailhost.<br> <br>
If you define all domain names in control/locals control/rcphosts, hosts will forward \
the mail to correct mailhost via QMQP protocol.<br> This is the same for POP3/IMAP \
sessions.<br> <br>

I am willing to try qmail+ldap. Some doubts arose!<br>
The scenario would be:<br>
<br>
1 ldap server,<br>
5 qmail servers,<br>
1K domain<br>
30K users.<br>
<br>
My doubt is the following:<br>
<br>
These 1k domain may be served by any of the 5 qmail server, ok? Will i have to \
include 5 mx recorder for each of the 1k domain?<br> That will make 5k entries in my \
dns server, is that right ?<br> <br>
thanks in advance.<br>
