Trace the ip address of the sender.

[Joe M]

Far out, these days a single spammer could enter any Names and any reply to
(from) address they like and send spam emails. They can even enter non-exist
email addresses and the recipients wouldn't have a clue where's it coming
from. Is it possible for me to find out the Ip address of the originating
emails? How????????? Thanks......
In the past 2 months, I have received over a thousands emails from Cialegen
and Viagra spammers.......How the heck do I stop them? It just comes from a
different email address everytime... ...........dammed annoying.

You can do this by opening the message and choose View-> Options. In the
bottom pane you'll see Received: from .....

Hope this helps!
