Hi,

I am developing a SMTP based program.
I construct both the client SMTP server and POP3 server on my PC so all the SMTP messages and POP3 messages are sent from and to the same PC. The problem is that when I try to capture the SMTP message with Wireshark, I failed. Nothing is captured.
Is it because the client and the server being in the same PC?
I have not any other PC so I have to do it on the one.

Any help or suggestion would be appreciated.
