Hello to u all mail experts,
We are running postfix mail servers in several locations around the world: 2 in CA US, 2 in TX US, 2 in London, 1 in Paris & 2 in Sydney Australia. In each production environment the servers sits 'behind' a vip for high availability. The main purpose of these mail servers is to relay outbound mail from our application servers to the Customers. Now we have a new requirement; we need also to accept mail for domain example.hp.com , we will create a mailbox for some application instance which connects to the mail server in pop3 to retrieve the mail. This is a totally new game where I have some concerns: - How to build a high availability solution where if one server fails the other one can also present the mailboxes which sits on a storage connected via nfs. - How to know where to route each message on the globe? ; From the best of my knowledge there are two basic solutions of this: o Either create a sub domain for each location : lon.example.hp.com, syd.example.hp.com etc... the drawback is that I need to maintain all these mail servers which accept mail with virus detection etc... o Other solution maybe to have one cluster which accept all mail for example.hp.com and route it via our internal vpn to the correct pop3account mailbox according to some transport map on the central receiving mail server. Has anyone run this kind of environments and get an experienced answer what would be easier maintain?
