Hi, I am trying to build a scalable Postfix cluster (Postfix 2.5.1) serving 1000 - 30,000 users with LDAP. The idea is to store the account information inside LDAP and build Postfix servers, such that each server serves its own users, e.g. user1 on server1, user2 on server2 .....
Virtual domain: auth.hk1.sml.citizen.co.jp
I try to use virtual alias, so that the e-mail destined to the virtual
domain us...@auth.hk1.sml.citizen.co.jp will be delivered to the canonical
address us...@server1.auth.hk1.sml.citizen.co.jp,
us...@auth.hk1.sml.citizen.co.jp to
us...@server2.auth.hk1.sml.citizen.co.jp....
It worked well by storing the virtual_alias_maps in hash table, but it
failed when changed to LDAP with an error "Error : 4.3.0 queue file write
error...". I checked the postmap and the result from hash is same as LDAP
:-
> postmap -q 'venus....@auth.hk1.sml.citizen.co.jp'
hash:/etc/postfix/virtual
venus....@imapsv02.auth.hk1.sml.citizen.co.jp
> postmap -q 'venus....@auth.hk1.sml.citizen.co.jp'
ldap:/etc/postfix/ldap-virtualalias
venus....@imapsv02.auth.hk1.sml.citizen.co.jp
=== begin of main.cf with LDAP ===

I hope someone could point me if it is a config. problem, or just Postfix
just do not work in that way (see attached error log).
Thanks a lot.
