I need to have postfix deliver email bound for a specific subdomain (e.g. websock.mydomain.xyz) to a websocket gateway I'm coding (in Node.js).
I've looked over the architecture docs, and would appreciate input on which delivery method is most simple/robust to implement. The messages in question are valuable, and my websocket clients often have unreliable connections, so I imagine waiting for client ack before accepting a message for delivery. I'm wondering about the overhead of having many concurrent delivery requests pending. I'm also wondering if it's possible/efficient to poke postfix when a client connects whom I know has messages pending (due to a previous delivery attempt). Liam
