When attaching any 'normally' named .EXE, my email is returned to me by Exim, with a note saying: "This kind of attachment is not good for you.....". If I rename the same .EXE to, say, (c).exe, it gets delivered and ZoneAlarm lets it in without quarantining it. Two bugs for the price of one! cheers Samps
