Market research company Colmar Brunton is upgrading its mail server in the hope that spam being relayed through it will stop.
New Zealand internet users have been hit with junk mail originating from a Colmar Brunton server in Sydney but the company’s Australia-based software developer, Ben Slabak, says an upgrade in the next month should solve the problem.
The company opens its server for four to eight hours each week to send out newsletters, potentially leaving it open to spam relayers. Colmar Brunton uses software called XtraMail (no relation to ISP Xtra) but will change to Microsoft Exchange with the relay function switched off.
“We keep regular checks on the open relay database on ORBS [now closed but an equivalent is at www.dorkslayers.com] where we are sometimes listed and we then take steps to get taken off.”
He says he was unaware of any spam going through recently but will look at fixing it. Colmar Brunton’s makeshift solution to the problem so far has been to switch between IP addresses.
