Hi, I am running exchange 2003 SP1 on windows 2003. I have installed Symantec 4.5 for excahnge on the exchange server itself. The problem is that even after updating antivirus with latest defination file the virus attachments (related to latest MYTOB virus) are getting deliverd to mailbox. So i am trying to filter these attahments out using filtering rules. I expect antivirus to detect this virus attachments without configuring any custom filters. Is there any thing i am missing. Anybody has any cluses. Regards Praveen R --------------------------------- Yahoo! Personals Single? There's someone we'd like you to meet. Lot's of someone's, actually. Try Yahoo! Personals
