Make sure your server has a host name. And make sure it is set up correctly.
If your DNS name is mail.gateshosting.com, make sure your server name is
"mail", and your suffix is "gateshosting.com" for a full name of
"mail.gateshosting.com". Also just make sure you HAVE a dns record for that
ip, and a rDns record for that ip.
Here is a tool I use to check my mail server: www.dnsreport.com - Just check
your domain name, like "gateshosting.com" and it will actually let you know
if you have any errors in DNS.
Also, I see in one of the headers, the ip address is You probably
should have a public ip address. Otherwise some servers will deny your
Hope this helps,

Ok. For me it is clear that my problem has to do with reverse DNS, and not
with SPF.
Can someone tell me how to setup right configuration for Reverse DNS for the
example i gave? Here is also an emailheader from a mail that is bounced:

I hope someone can tell me what to do with my DNS settings here, or if it is
not my DNS, please tell me where to look.

Please be aware that there is an official SPF resource record.

But do publish TXT records for your SPF rules as well.  The RR is brand
new and isn't used that much yet.  Eventually only the SPF resource record
is going to be used.  This will take time.

Let's not discuss SPF here.  If you want to know why it is the user's
fault and not the SPF record's fault, let's meet on the spf-discuss
mailing list.
