Asunto: [exim] Virus scanner - changed return string
I recently got caught my McAfee when they changed the return string. Not a problem once I figured out what was going on ;-) I thought I'd share my modified script with readers as I got the original off here ages ago..... (excuse the line wraps)

Cheers
