Right, but this is M$'s fault for setting Explorer to hide extensions by default. > Chances are the list in question will not let this in because it's > extension is .vbs not jpg.

My solution is to use Linux with Mutt as a MUA; no trojan/virus/worm concerns and without the necessity to update antivirus software. Many (most?) listowners do not have the option to scan messages before they are posted to a list. I attempt to protect those who insist on using broken software by not allowing attachments and setting a short maximum message length. Luckily, most malware is fairly big these days. Not so in the past: I've got a virus in my zoo of ~5000 that is less than 30 bytes long. Regards, -rex
