True so it's not really possible.Originally posted by: bozo1
Nope.
You can send your email with a return receipt requested but the recipient can always choose not to send one.

Heh, Outlook Express can display text only now. 🙂
How exactly can you figure out when somebody has read an email just from being on a LAN with them?

listening to port 110 tells you about traffic. trying to see if someone has actually opened up mail, now you are going inside someone else's computer and seeing if the mail was viewed. Noc's suggestion is brilliant: A 1 pixel by 1 pixel image in an html message, is really a link back to a server of yours. when that link is activated, you can have the server keep track of the hit on it. you will know when someone viewed the mail message. The reader will see nothing in the body of the mail.
It is kinda cumbersome, but it works. Very high on geekiness content😛

i'm guessing you can tell an email has been opened by someone on your LAN through a network monitoring program, maybe listening on port 110 (POP) - is this accurate??
