Answer 1

You are using POP3 commands with an IMAP server. They are not compatible, and their language is very different.

For one, every IMAP command has a tag, and basic logging in is done with a LOGIN command. It would look something like this:

a001 LOGIN user@gmail.com "password"

If you want to use POP3, connect to the pop3 server at pop.gmail.com, with TLS enabled on port 995.
