First. I am on a small email distribution list. The "owner" is having a problem. He sent out a message yesterday. Then it came a second time. He sent out a retraction. The original message came a third time, the retraction a second. The he sent out an apology for the multiple messages. So far we have received over 200 messages from him. And he does not know what is causing it or how to stop it. His "computer technician" cannot stop it either. I'm assuming IE and Outlook. Suggestions on how to stop sending? They're still arriving, about 3 every 1/2 hour.
Second. Is there a way I can determine which browser someone is using from an email sent?
