If you enter your domain at dnsstuff.com for testing (http://www.dnsstuff.com/tools/dnsrep...=ctisystems.se) you see at least part of your problems
Code:
FAIL	Missing (stealth) nameservers
FAIL: You have one or more missing (stealth) nameservers. 
The following nameserver(s) are listed (at your nameservers) as nameservers
for your domain, but are not listed at the parent nameservers (therefore, they 
may or may not get used, depending on whether your DNS servers return them 
in the authority section for other requests, per RFC2181 5.4.1). You need to 
make sure that these stealth nameservers are working; if they are not 
responding, you may have serious problems! The DNS Report will not query 
these servers, so you need to be very careful that they are working properly.

sbs.ctisystems.se.
This is listed as an ERROR because there are some cases where nasty problems 
can occur (if the TTLs vary from the NS records at the root servers and the NS 
records point to your own domain, for example).
Why you're getting a reverse DNS reject, I don't know (yet). There must be someting more wrong, because trying to resolve the IP addresses gives a servfail, which means rDNS is not setup at all:
Code:
