your question is unclear. you may want to show an example.
do you mean that
- if mail comes "from" x...@domain.tld, then
- if IP is in some set, then it's ok
- else reject
if so, then create a restriction class,
smtpd_restriction_class =
...
dont_foo
dont_foo =
check_client_access cidr:/etc/postfix/foo_ok
reject
smtpd_sender_restrictions =
check_sender_acces hash:/etc/postfix/foo_sender
== foo_sender:
j...@example.com dont_foo
