TCP/IP doesn't have any particular port no But It is a name given to IP address with other protocal set that Defien the Port on on the IP address.. And hence the TCP/IP is More than a port no.

An IP address have different port like 10.10.10.10 is a Ip Address and 80 is port no to access awebsite on this IP address.

Hi..

Even i think it is not possible to send mail through port 80 without the sever configuration. You need to make your server to send mail using any port. In gerneal it is only port 25 (IF i remember correctly ) for smtp.
