I am very new for Hmailserver , I have setup hmailserver in my network :
I am facing issue with email sending out from my domain , while I am able to access email from outside world.
following is my mail server setup information
Hmailserver 5.3.3 version on windows 2003 R2 server I assigned static private IP address on server. I created MX record for my mail server pointed to my firewall. Firewall have NAT of private IP to public IP . Port 25 is working in both direction. I am able to do SMTP telnet from server machine to mail.hmailserver.com on port 25.
When I am using hmailserver diagnostics getting following error :
Test: Test IPv6 IPv6 support is not available in operating system.
Test: Test outbound port SMTP relayer not in use. Attempting mail.hmailserver.com:25 Trying to connect to host mail.hmailserver.com... Trying to connect to TCP/IP address 188.8.131.52 on port 25. ERROR: It was not possible to connect.
