why? postfix shouldn't be using tcpwrappers. postfix has all the functionality in itself. > >> Also if you are use acl's on shithes/router also check them. >> show access-list >> > > Both servers are connected to the same switch, it has no access lists. > since postfix seems to be listening on its ports, if you can't connect, then something is preventing that. This may be a firewall (yes, even on localhost) or any intermediary layer. anyway, if you don't see postfix logs, then you didn't reach postfix, and this is not a postfix issue. good luck.
