I am facing one issue which is mostly about concepts. I have to be clear on that to move forward. I have tried finding solutions about it but couldn't find anything which talks about it.

We have a setup which includes postfix and dovecot. We are using lmtp and delivery of mail is happening through dovecot. We want that delivery of mail should happen in a separate node. I was able to achieve it through lmtp by providing ip address and using port 24.

But now I have been asked to just try to deliver to a separate storage medium and not node. That means it will have an ip address but no dovecot or other software running. This is in relation to incorporation of storage area network (SAN) later on.

Is it possible? I thought there must be some way as many running mail systems are using message store and SAN. All i can find that was close was mailbox sharing and email archiving.

Please help me about this as I have already spent 3 days to it with no luck. I just want the right direction to move forward on this.

Regards
