Zdziwiłem sie dziś przeglądając porcje deferów z mojego domowego
serverka że nie wyszły wiadomości do aol.com.
Wszystkie mxy odrzuciły połączenia.

To tak dla przypomnienia:
$ host -t txt aol.com
aol.com text "v=spf1 ip4:152.163.225.0/24 ip4:205.188.139.0/24
ip4:205.188.144.0/24 ip4:205.188.156.0/23 ip4:205.188.159.0/24 
ip4:64.12.136.0/23 ip4:64.12.138.0/24 ptr:mx.aol.com ?all"
$

Host bez ptr (z ptr zresztą też):
$ nc mailin-01.mx.aol.com 25
220-rly-ya01.mx.aol.com ESMTP mail_relay_in-ya1.4; Thu, 18 Mar 2004 16:11:04 -0500
