I wrote this simple plugin, mxpf
This plugin search B class of sender Ip Address and try to match B class of any
Ip of mx records of declared domain
So when it match is very difficolut that sender is a spoofed domain, you can
use MXPF_PASS to combine with other rules in addition to SPF_PASS
1) Unpack mxpf.cf and mxpf.pm under /etc/mail/spamassassin dir
2) put your score in mxpf.cf

that looks really good
on piece missing - something like "whitelist_mx" working the same way as
"whilelist_auth" to combine it with shortcicuit to complement whitelist
by spf with that for senders you trust but don't have SPF/DKIM for
whitelist_auth
whitelist_mx sen...@domain.tld
whitelist_mx *@domain.tld
