Spammers get the boot from web host

Web hosting and connectivity company Savvis Communications has cancelled about 40 accounts, at a cost of as much as $2m per month, from businesses that were earmarked as spammers and believed to be among some of the worst bulk-mailers.

Savvis halted the accounts after anti-spam organisations notified the company that it was providing web hosting services to known unsolicited emailers. The spammers in question were listed on the Spamhaus Register of Known Spam Operations (Rokso), a blacklist used by many internet services to curb spam volume on their systems.

Spam blacklists highlight one controversial front in the battle against unsolicited email. Blacklists are typically compiled by volunteer organisations that monitor alleged spammers and many companies and internet providers block those listed.

These lists have come under scrutiny by critics who allege they block legitimate businesses that do not violate US laws.

All Savvis customers listed on Rokso were longtime clients of Cable & Wireless US, which the company acquired in March this year, CEO Robert McCormick said.

Further distancing himself from these clients, McCormick said Savvis would have never allowed these alleged spammers onto their web hosting service.

"This is not a problem we created," he said in an interview. "Not a single one of these contracts were signed by Savvis."

Savvis's move came shortly after internal memos were leaked onto the web documenting a debate among executives over how to take action. In the documents, executives weighed the merits of cancelling accounts to preserve its reputation, and whether the companies in question were violating any laws to warrant action.

Kris Kistler, Savvis' director of InfoSec and abuse, wrote in a memo: "Without a good reputation as a secure and honourable provider, Savvis will soon start to lose its ability to sell to upstanding corporations and business leaders, and instead fall to its own vision of providing service to spammers and other 'unwanted's'."

One executive speculated that cancelling the 40-or-so customers could cost the company between $250,000 and $2m a month in revenue. Savvis' McCormick said the monthly cost was closer to the $250,000 end, but declined to give a solid number.
