I work in a mixed platform environment where I need to permit unauthenticated hosts within our LAN to send email so the UNIX and embedded systems which use SMTP directly can work, but I would like to prohibit road-warrior clients from sending to port 25 unauthenticated (remote access to our mail server is a requirement).

Put your LAN addresses in the Settings => Network =>Lan IPs =>Lan IP Addresses.

for example:

then go to  Settings => Network => Client IPs

and check "Process LAN IP adresses as Clients".

and mail from them will be allowed.
