Hello.

I've sucessfully configured proxmox mail gateway 7.1 to filter incoming messages for my Exchange 2013 mailserver however I have a problem to setup outgoing mail. For now Exchange sends emails directly to the Internet. I've tried to change send connector to route mail through smart hosts (proxmox IP address) but it doesn't work. Can anyone please share their experience on this subject?

Did you configure the exchange server to send the outgoing emails to port 26? the Mail Gateway accepts incoming mails on port 25, and outgoing on port 26.

Yes. I did.

Set-SendConnector -Identity "Proxmox" -Port 26

Ok. Mystery solved. Added port 26 to firewall rules and it's working now.

You have to add recieve connector on port 25 in ECP. In remote network settings add IP of your proxmox mail gateway server.
