A software application that enables you to connect to any tcpip port on a machine and send it linefeed-terminated text.Sender enables you to connect to any tcp/ ip port on a machine and send it linefeed-terminated text.As such, for example, you can manually use Sender to check a pop3 inbox (if you are familiar with the pop3 protocol).Sender also has a server module, so it can act as a tcp/ ip server on a user specified port. This enables you to emulate a server which will use linefeed-terminated text manually if necessary.Sender was initially started because I had forgotten my email password, but my email client still had it. By emulating a pop3 email server, and pointing the email client at it instead of its regular mail server, I was able to retrieve my forgotten password.
