Did the new Blackmal (Small.KI) hit you? How could SF help to keep it out?  I filter executables but there ones seem to be into a MIME attachment SF does not consider

Clutcher,

Exactly what are you asking?  Parsing 2 days of my SpamFilter Logs show that SpamFilter DID block the virus.

Clutcher,

Are you using the anti-virus plugin? If not, please note that the attachment filter in SpamFilter can be fooled by some viruses. SpamFilter by itself can help to block a large number of viruses using its filters, but some will always slip thru. That is why antivirus software is really needed to ensure better protection.

Yes, I'm using antivirus plugin that on 18th started detecting  Text/Small.KI but on 17th several .hqx attachments passed Norman and SF Inside those encoded attachment there where .scr or .pif executables.

(Just for the record, NAV on Domino started blocking them form the very start)

I'm really thinking about asking for and implementing a white list for attachments.

Unfortunately if there is no pattern yet for a virus the plugin won't be able to stop it. Sometimes one company releases signatures before others, and sometimes it's the others who release them first. There will never be a winner...
