Things were probably unsettled while I was messing with the mail software here, but that's been up and running in its present form for a few weeks now. I was on a different machine Friday morning, which probably made the difference but I don't know how. On that machine I use Outlook Express on XP Pro. OE goes outside the LAN and sends mail directly to the server at Embed. The message I'm writing now is from OE on a Windows 2000 Machine at Embed, which will send it to the same server as the other one. To the outside world, both messages are coming from the same software at the same IP address. I can't think of how the server would distinguish the two messages by anything it should be looking at. The last (oldest) "received:" line would be different, but the server shouldn't care and probably doesn't even examine it. I have sent messages successfully to the PIClist from the other machine in the past. Any ideas how to diagnose this problem? ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
