prevent other machines to connect to proxmox

[Cloos]

Our E-Mail is always send through and from the providers mail server. Is there an option to restrict the connection to the proxmox mail gatway to our internal mail server and the mail server of the provider? Our internal mail server resides in the same subnet as the proxmox mail gateway.

Thanks

hi,

yes, but some settings has to be done on your (separate) firewall, not on the mail gateway.

Proxmox has an internal list of allowed IP addresses, see Configuration/Mail Proxy/Networks - Internal (trusted) IP Networks/Hosts
