Hi Friedrich
Yes correct.

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 ?

Hi Friedrich,
You do not have to setup 5 mx. If you distribute users on qmail backends via \
mailhost entry on LDAP. Just create a A DNS record for each mailhost. and define a \
MX record has 5 IP address.
example dns settings for all domains:
IN MX mx.mymasterdomain.com
mx IN A 192.168.1.1
mx IN A 192.168.1.2
mx IN A 192.168.1.3
mx IN A 192.168.1.4
mx IN A 192.168.1.5
mail1 IN A 192.168.1.1
mail2 IN A 192.168.1.2
mail3 IN A 192.168.1.3
mail4 IN A 192.168.1.4
mail5 IN A 192.168.1.5
Do you have any antispam gateway in front of the mail servers? If you have,some \
antispam gateway solutions have a feature to lookup mailhost entry on LDAP and \
directly forward email to correct mailhost.
If you define all domain names in control/locals control/rcphosts, hosts will forward \
the mail to correct mailhost via QMQP protocol. This is the same for POP3/IMAP \
sessions.
Thanks

Hi.
I am willing to try qmail+ldap. Some doubts arose!
The scenario would be:
1 ldap server,
5 qmail servers,
1K domain
30K users.
My doubt is the following:
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? That will make 5k entries in my dns \
server, is that right ?
thanks in advance.
