Only if they have fixed IP addresses.
Think about what you're asking for, a method of authenticating a
sender. You need something to use as a credential that's imposable
to or very difficult to forge.
If you are unable/unwilling to require that your users send you an
authenticating token (e.g. AUTH password) then about the only thing
left is the IP address the request is coming from.
