Market research company Colmar Brunton says spam originally thought to be going through its Sydney server, is coming from elsewhere. A New Zealand spam victim who pinged the junk mail server found it belonged to Colmar Brunton.
Colmar Brunton originally accepted liability because it has to open its Sydney-based mail server regularly to send newsletters. However after further investigation, the company’s software developer Ben Slabak says spam has not been going through the Colmar Brunton server. He believes someone else may be spoofing Colmar Brunton or masking another server making it look like it belongs to Colmar Brunton. He is looking into it further.
Although Colmar Brunton has to open its mail server, making it vulnerable to spam relayers, it plans to upgrade to Microsoft Exchange to solve the problem. Despite having the server sometimes open, no spam has gone through because it uses alternating IP addresses.
