You don't want to rely on the sender address for *anything*; it can
trivially be forged.
When you say "relaying", do you mean "inward" or "outward" relaying?
Looks like you mean "outward", in which case you can put something like
this on your router:
condition = ${if eq{${mask:$sender_host_address/24}}{192.168.1.0}}
That, of course, applies only to a single network. Unfortunately, there
isn't yet a match_ip_address condition to match more than one network.
You would have to write something messy with "and".
