mail reader and mail server protocols

consider the following question
what protocols can be used between a mail reader and a mail server?

Is HTTP a correct answer? I'm asking because I have some disagreement and need to get a credible answer.

There aree a number of protocols used by email clients/servers:

The POP3 port for inbound emails is 110 (995 if you want to use secured POP3)
And the IMAP port for inbound emails is 143 (993 if you want to use secured IMAP)
The SMTP port for outbound emails is 25 or 2525 (465 if you want to use secured SMTP)

Http(s) isn't quite a correct answer. This is when using webmail and when using that a webbrowser is used, so you could consider that being the 'client'.
