It is possible in some way to configure postfix, that SPF Passed mails
will be automatically accepted with postfix without greylisting?
If I may be blunt: this is a really dumb idea. Many, maybe all,
snowshoe spammers have valid SPF records. Thus, accepting mail simply
because the connecting IP passes SPF muster isn't a bright idea.
some even use an indirect +all to trick filters...
$ host -t txt takeprettypictures.net
takeprettypictures.net descriptive text "v=spf1 ip4:128.0.0.0/1
ip4:0.0.0.0/1 -all"
(so the first bit must be 0 or 1. since a bit is either 0 or 1...).
do you like sendmail machine
that adresse is unauthorized for me
There's no "address". the SPF record above specifies subnets with a /1
mask, the union of which is the whole IPv4 space.
