I'm just using Outlook Express, and it does whatever it does. "Main" is the local name of the machine I was on within the embedinc.com local network. I'm not sure whether there is any information on that machine for OE or anything else to figure out the external IP address is assigned to the embedinc.com domain. And no, I don't want 15 replies suggesting how I should be using this and that mailer, some non-MS operating system, or whatever. I've got things to get on with, and worrying about the standards conformance of my mailer when it doesn't effect me isn't anywhere on the list. ****************************************************************** Embed Inc, Littleton Massachusetts, (978) 742-9014. #1 PIC consultant in 2004 program year. http://www.embedinc.com/products -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
