So, when someone says "RCPT TO:<something@???>" you want to
reject the command, unless they are connecting from some nominated list of IP
addresses? And does that list of IPs vary depending on the domain? (I'll
assume it doesn't, in my example below).
Something like:
domainlist restricted_domains = some.restricted.domain : another.restricted.domain
hostlist ok_senders = trustedserver.example.com : 10.0.0.0
to define the domains and IPs in question, then
deny
domains = +restricted_domains
!hosts = : 127.0.0.1 : +ok_senders
message = Not allowed
in your acl_smtp_rcpt should do the trick.

You don't have to use a domainlist / hostlist as I did above, but
fundamentally the answer is to add an acl_smtp_rcpt stanza using the "domains"
and "hosts" conditions.
