If I wanted to use SPF in spamassassin to block spoofing attempts
against my domain, how would I do that?
Can I create a meta that combines SPF_FAIL with the From header for my
domain to do this?
setup pypolicyd-spf is not that hard is it ?
when done, you just configure the spamassassin plugin to reuse the
recieved-spf header
data in spf must be with all mynetworks in postfix except all non
routeble ips such as rfc1918 in the spf for mydestination and virtual
domains
before going live with it, check spf in kittermanns and or dmarchian is
valid, not after as many do in the past, i have seen ip4:192.168.00/23
in an example fail in my logs, no rfc 1918 dont need to be added to spf
