You could do this in acl_smtp_rcpt. Something like (off the top of my
head):
1. Define the hosts (IPs)
hostlist allowed_hosts = 1.2.3.4 : 3.4.5.6/30 : a.b.c.d/NN
2. Define those domains you want to accept mail for as a domainlist.
domainlist those_domains = blah
Now, at an early stage in acl_smtp_rcpt:
deny condition = ${if match_domain {${domain:$h_to:}}{+those_domains}}
!hosts = +allowed_hosts
I am not sure how this will deal with cases where recipient is in the CC
or BCC though.
