Hi,
We have a business requirement to enable POP/SMTP/IMAP from internet to our Exchange servers (though they are legacy protocols)
Where to check the client access logs for the above protocol connections (Is it IIS logs?)
Particularly in cases like end-users are traveling abroad and need to check from which internet IP they have connected (in certain dispute cases) I believe this log can be used for checking brute-force attack sources also
Thanks
