Yesterday, the Do Not Call Registry was started. More than 735,000 people registered on the first day not to receive any calls from telemarketers. Their website was difficult to access all day because of the high load.
“Our tests showed that Yahoo’s spam filter was automatically sending the confirmation messages from the do-not-call list into users’ bulk-mail folders,” said NetFrameworks co-founder and CTO Eric Greenberg. “The irony of it is that the spam filter is blocking the very thing that’s supposed to help you stop getting spam over the phone.”
I think I had the same problem yesterday with Hotmail. The spam filter probably automatically deleted the emails from the registry which are needed to complete the process.
