Our activation system (i.e. e-mail confirmation) has been off for a few days – it’s been fixed up now. There was quite a lot of emails that were unsent. So we pruned the queue, all activation emails that were requested were pruned, all private PM notification emails were pruned, all topic reply notification emails were pruned. This decreased the queue by about 30K to 15K atm. The emailer will begin to send emails as of now.
The reason why the emailer system broke down is because the recent DoS to the network has caused MySQL to notice failed connections from our mail server and denied it access.
