In Yahoo Mail, each message "Title" in my Inbox is actually a link, so what I did was right-click and then copy the shortcut, then paste it somewhere else like a Google search box where I could see it in detail. What I got ended with:
....kTA&f=1&fromId=A38C2A52@podmostem.cz [Highlight Added]
Which looks very suspicious at best. A Google search of the last part (podmostem.cz) brought up sites about an inn in Czechoslovakia and such, obviously nothing I'm interested in or want anything to do with.
My question is whether there's a better way to get this information and additionally, if one is using pseudoaddresses such as are available in Yahoo, how can one determine which address a message was sent to, something my method above won't determine. Any suggestions, comments or corrections are welcome.
