Hi,
I have the following setup. I have a client who has 10 offices across Mumbai. Each office has approximately 50 people on the LAN. All offices have a linux server that connects to a central office RAS via dial up. LAN users can then access servers located at the central office for nightly database updates etc.. All IPs used are RFC 1918 non-routable type.
I want to install mail services for the client. A mail server will be placed at the central location. This mail server will be connected to the internet and receive all mails destined for the organisation - say fooabc.org. There will be mail servers at each branch office also which will handle intraoffice mail - i.e. mails within a single office.
I want to know if we can use the same domain name say fooabc.org at each branch location. Essentially, when each branch mail server receives a mail for userA@fooabc.org, it should look up a table(or whatever) to find out if userA exists locally in that branch office. If userA exists then it should keep the mail locally. In case userA is at some other location, then the mail should be forwarded to the central mail server.
I have a faint idea that LOTUS DOMINO does something like this. I want to do this setup with qmail, I am pretty conversant with qmail and have a few installations also. Can this be done?
If not, then how can the same be achieved? Please suggest.
Regards, Ashok
