Hi Guys,

I need help, I must be missing something I have setup proxmox for my exchange 2010 environment, I have set the connector to point to proxmox which is my smart host, I have done all white listing for trusted emails and domains and setup my relay as well. but I can receive emails only I cannot send. what I send does not get to the receiver. When i check the queues the sent emails seem to be rejected.

Please help.
 
Most likely you send mails to the wrong port.
I have my external SMTP port set as 25 and internal as 26 my whitelisting is ok but what i can see is all emails from my domain sending to outside are rejected. I am not sure what I am missing.
