devels.es is your own server, so postfix reports a loop. Where should outgoing mail be delivered? Directly to the receiver's MX? relayhost should be empty. To your ISP for delivery? relayhost should point to their smtp server. An internal mailhub/smarthost? use the IP of the internal hub. -- Noel Jones
