[PERDITION-USERS] DNS maps

Hello, I'm trying to unify backend server maps in a local DNS server: Internet HTTP -> reverse proxy [queries DNS] -> backend HTTP servers Internet SMTP -> reverse proxy [queries DNS] -> backend SMTP servers Internet POP3 -> reverse proxy [queries DNS] -> backend POP3 servers Internet IMAP -> reverse proxy [queries DNS] -> backend IMAP servers Instead of make a database map for each proxy, I'm setting up a virtualhost system based on proxies that query local backend servers as if they were in internet: with DNS maps. I want to know if there is a way to do this with Pertition, without maintaining a dedicated database: Internet IMAP petition (guided with internet DNS) -> Public firewall with a single IP -> Perdition (guided with LAN DNS) -> each backend server. EXAMPLE 1: MUA asks for imap.example.com Internet DNS maps MUA to 80.80.80.80 -> Firewall to the LAN -> 1 Perdition asks login to MUA user 2 MUA gives username narcis(a)example.com 3 Perdition is configured to replace user@* by imap.* and asks for imap.example.com 4 A local DNS answers imap.example.com A 192.168.1.5 Perdition -> backend IMAP server 192.168.1.5 Thanks.
