i dont know if amavis has options for that

you may have a look at

https://github.com/croessner/vrfydmn

to use it with postfix/submission

perhaps ask the author to integrate ip/subnet matches or combine it
in milter-manager with a ip/subnet filter

http://milter-manager.sourceforge.net/reference/configuration.html

never tested...
