Microsoft is aware of an issue with the SpamCure engine not updating and detecting spam in Antigen 8.0 and 9.x products since August 1, 2008. We are working with the engine vendor to resolve this issue and will continue to update this blog as more information becomes available.
Customers running the Antigen 8.0 and 9.x products may experience spam detection dramatically drop if they only use the SpamCure engine to detect spam. To attempt to detect spam while Microsoft works to resolve the issue, you can configure the following options within Antigen:
- Mailhost Filtering:
Add one or more RBL servers
Add known spamming Mailhosts to the Rejected Mailhosts
- Keyword Filtering:
Enable the default keyword lists
- Content Filtering:
Add known sender domains/subject lines of spam
We apologize for the inconvenience and do hope to have this issue resolved as quickly as possible.
