Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Please clarify what a port address is? I use specific port address for smtp and I see a different port address for my internet browsers. Is the port number I use for sending mail in my perl scripts dependent on the software application I am using?? For example if I use Cold Fusion to send mail I would use a Cold Fusion port number? But perl would use its own port number?
