Still Relay Acces Denied. POP3 port 110 open.
Dont know why it blocks.
PTR record must be created by my ISP?
My hostname is vectranet.pl, but my domain is different, so revDNS for my IP do not point to my mail domain.
Here is my bind9 zone file:
220.127.116.11.in-addr.arpa. IN PTR guid.pl.
guid.pl. TXT "v=spf1 ip4:18.104.22.168 -all"
