Of course I do.
then you use something like "check_policy_service unix:private/spfpolicy" to deny any email claiming to be from @your.domain that wasn't sent from your mail server IP.
For some reasons I'd like not to apply restrictive SPF checking. For envelopes my simple solution works perfectly without SPF. How about internal "from:"
