Recently I install a 3rd party Vendors anti-spam application.
Below is part of the configuration requirements. (Names are changed)

Outlook Express 5.0,tools,accounts,isp,properties button,server tab,
Server Information
Incoming mail [pop3]: 127.0.0.1
Incoming Mail Server
Account Name: pop3.isp.com/110/jjrhody
Password: *********
Remember Password.

When I view the (Pop3.log) I noticed that orginally it was this way:
POP3: 09:52:42 [rx] +OK POP3 server ready
POP3: 09:52:42 [tx] USER jjrhody/pop3.isp.com

After Installing Vendors Software it's now this way:
POP3: 02:37:34 [rx] +OK TSA - Version 4.10 - http://Something.cam ready
<137699281>
POP3: 02:37:34 [tx] USER pop3.ix.netcom.com/110/jjrhody
When I did a ping and who is on "real" Ip address it came up as the Vendors
Name.
What is going to the vendor from the machine is the Question?


This is a sample cut and paste from the log.
