For those of you that are using our EECS spam service, here is an update.
After months of service degrade, the vendor finally concluded that our spam appliances have been “poisoned” inadvertently due to the overall setup within EECS. That is why we are seeing less than optimal success rate, indeterministic tagging of emails, etc.
The only way to resolve this is to do a complete reset of our spam configs. We will do this on Tuesday, 3/29/05, at 9am. There will be no downtimes. We will do as much pre-training as possible, especially for false negatives. The extra taggings will continue.
As a user, you might see some false positives/negatives, which you should send them to helpdesk (help@eecs), along with the complete header. If you opted out of the auto-filing on IMAP server, this will not have any impact. Please also let us know if you encounter any other problems.
