hello, i need help.. im trying to send email from postfix to exchange server (same network) but connection refused, but when i send email from exchange to postfix it successfully received. I tried to simulate this problem into my lab room (same set up of my production environment) i can send/received email from postfix to exchange (vice versa) and no problem occurs. Is there any problem with my postfix configuration? or in my windows environment? Please help
Connection refused is usually a simple networking problem. Just use telnet to verify that you can connect to the exchange server on port 25 from the postfix box. Code: telnet exchange_ip 25
