Re: How is this possible ?
BCC is one possibility, forged headers is another. Short answer: a message has two components: the P1, or envelope, and P2, the body. For SMTP the addressing in the P1 does not have to match the addressing in P2. P1 gets the message delivered, P2 is what populates the message fields. - Original Message - From: "RBHATIA" <[EMAIL PROTECTED]> To: "Exchange Discussions" <[EMAIL PROTECTED]> Sent: Wednesday, February 27, 2002 9:42 AM Subject: How is this possible ? > I have a user who received an email where the TO: field showed a > 'bellatlantic.net' email address (which he claims he doesn't own).

Is this possible?
Hi there... Sorta OT - but just wanted to pick the brain of a bunch of mail admins. Our company sent out a Christmas greeting this am that was an html email, but with nothing more than a link to a flash movie online (self produced) on our web server... One of our clients said that as soon as he opened our email his outlook closed down, and he can't get back into mail. The client never even clicked the link or anything... He barely even had a chance to look at it. There were no attachments... Just a link on the format of: http://www.server.com/page.html I don't see how this is possible I wanted to be sure before I put this one up to chance. Thanks in advance!
