Solution 1

Your mail server's SMTP address is definitely not on port 80.

Contact you mail servers admin and ask for the SMTP port number (default is 25 but it could be something else).

Solution 2

The same reason that all your other versions are not working. You really need to spend some more time studying this class[^] and its associated objects. You then need to learn how to access the smtp port of your chosen host. If necessary look at the host system's help to find out the correct host name and port number to use. And finally, make sure you have chosen a host that actually provides an SMTP service.

Thanks. I don't know if you've been following OP's questions on this subject but he clearly does not grasp what SMTP is about.
