hi folks, We need to deploy a qmail with LDAP for address book and authentication at several of our offices spread over the country. We'll be putting one central server at our data center, with an anti virus gateway for it.So its a hub-n-spoke kinda architecture.All mails to-n-fro the Internet will pass thru this central server. some issues that i'd like help with:

1)i need a single domain ( company.com) to be hosted across these multiple mail servers

2)Intra-office mail, i.e mail from an user to another user in the same office should be delivered locally.

3)Mail for remote user i.e.one situated at another location should be routed to that location's mail server, but through the central anti-virus gateway.

4) All users have a common web interface for changing passwords

5)In case of qmail,how can i have some accounts on the local server and then instruct the server to send mails to some other user but belonging to the same domain to some other smtp sever.. this without LDAP.... i.e user1@company.com wants to mail user2@company.com but user1 and user2 are on diff machines .. LDAP is not involved in the picture i want mails to go thru a central mail server!!!!

I guess this might sound a little confusing, but i'm sure most of ya guys will get it!

any help appreciated!

regards, kishor
