Dear Folks,
We receive an e-mail that we want to reply back, but the sender's SMTP is=
NOT
registered in DNS. Let's say the sender is who@xyz.com.
Let's assume xyz.com is being resolve with its ISP DNS 150.150.150.1. Bu=
t
there is no MX for xyz.com in this DNS.
Our e-mail is MS Exchange 5.5. Can we trace the sender's SMTP IP address=
?
Is there better way than to peel off the original header packet to see th=
e
sender IP?
Thanks,
Audie Onibala
