I have successfully configured Proxmox to filter mail coming from our external mail gateway, but when I try to use it as our outgoing smtp server I get the following error:
NOQUEUE: reject: RCPT from CLIENT[192.168.1.43]: 554
<yyy@yyy>: Relay access denied;
from=<xxx@xxx> to=<yyy@yyy>
proto=ESMTP helo=<[127.0.0.1]>
I suspect that the different mail proxy ports may be the reason. What is the reason for different "Internal" and "External ports when both "Ports" are on the same network??? I have changed so that both are port 25 (which makes sense).
