Hi,
We are using MS Exchange 2010 with HUB and CAS on same Server and third party SMTP Gateway is used for external mail flow.
We came to know that some unwanted mail has been sent and We wanted to know the source/origin from which machine/IP mail has been sent.
1) We wanted to whether mail has been sent from internal Network or Internet.
2) Wanted to know the Source Machine/IP even if mail has been sent using Internet like OutlookAnywhere or OWA etc.
3) We also wanted to know how to track if some one is sending mail from external id like Yahoo,Gmail to Exchange user and we wanted to know the source Machine/IP.
Kindly help
