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.
