I am attempting to set up Proxmox for the first time feed external emails via SMTP 25 into Proxmox and relay the data to an exchange environment. For the sake of arguments my external email address is mail.default.com.

Relaying:
mail.default.com
25
SMTP
No
None

Relay Domains:
mail.default.com

External SMTP Port:
25

Transports:
mail.default.com
10.0.0.30 (host for exchange environment)
SMTP
25
No
External Mailserver

What am I missing? Why do I continue to get relay access denied error message?

Thanks!
 
Are you trying to send from external to internal mail server, or the other way around?
If you're trying to send from the internal to an external one, you have to use the internal port of the PMG (26 by default).
 
I am attempting to receive an email from an external port 25, and pass it to the mail server that is internal after receipt from Proxmox. So it is my understanding that Port 25 would carry it all the way to the exchange box? I am unconcerned with external email traffic at this point.

If my assumption is incorrect, please let me know.
 
Please provide the logs from such an attempt. You can find the relevant info in /var/log/syslog.
Just to be safe, please provide ~5 minutes before the attempt until 5 minutes after the attempt, so 10minutes in total, of the syslog.
 
This is an example of failures happening when Port 25 is switched to Proxmox. I switch back to exchange directly when not testing.

Is the domain in 'Relay Domains' correct? (reichnetwork.com according to the logs)
Please post your 'Relay Domains' and 'Transports' configuration.
 
You have to add the right relay domain (reichnetwork.com, as seen here: kovit@reichnetwork.com) if you want to relay mails for that domain.
