Small home network, Win XP, IE 7, OE 6, all updates

Have received email from two different people. Each has it's own distinct
email address, but both have the same IP Address in their "Message Source".

Is there a way to tell if both these messages came from the same computer?
Can't locate any guidance on the Internet.

Thanks

Not unless the email went through a local server. I have four computers
running behind a router. The only IP address you would see (normally) is the
IP address of the router because that is the IP address the SMTP message
submission server I normally use sees. On some rare occasions, I use an SMTP
message submission server built into the Windows XP MCE 2005 OS; and, in
that case, that server will stamp the computer IP address in its headers.

Not with much reliability.


Thanks

If they're from the same domain:
and especially from people on a LAN, it's quite possible they are
different people. If they came in quick succession but not from a LAN
based computer where everyone uses the same gateway, then they should
have different IPs. It's a pretty good coincidence, but IPs do get
reused so if one person reset his router and the IP went to another
person, it would appear they'd both be the same machine, but that's an
awfully big coincidence.
Sometimes IPs change often, sometimes they don't; it depends on the
ISP.
