The error message is telling you that your domain was not verified for some reason.  Go to http://www.mxtoolbox.com/ and enter the domain name that is used to send your email.  You will get a lot of information about it like whether it is listed as a source of spam.  Check for SPF.  If you don't have it, go to http://www.microsoft.com/mscorp/safety/content/technologies/senderid/wizard/ and create it to put in your nameserver records.  Fix any other mail server problems you find at http://www.mxtoolbox.com/

The only discrepancy I found was that the PTR record did not return your domain name.  It comes back with 236.233.86.203.pacdns.com .  Everything else looks just my domain name.

Because of this:

220 hkitec.net ESMTP
OK - 203.86.233.236 resolves to 236.233.86.203.pacdns.com
Warning - Reverse DNS does not match SMTP Banner

'hkitec.net' in the initial 'banner' does not match the Reverse DNS of 236.233.86.203.pacdns.com  they need to fix that.

And your domain has the same problem.

220 cttlhk.com ESMTP MDaemon 9.5.6; Mon, 19 Mar 2012 17:32:27 +0800

 OK - 218.189.175.58 resolves to citizenthunderbird.com
 Warning - Reverse DNS does not match SMTP Banner
