       | Or if you want a queue, use AMQP.

       | A POP3 service seems like a very niche thing to want to write.
       | Especially nowadays, with people reading their e-mail on multiple
       | devices and wanting to keep them in sync.

       | open and use the pop feature.

       | The pop protocol is so simple it's a fun toy to write, as well.
       | You can do pop against most mail providers. It's not very secure
       | of course. But has value as a learning tool, too. Knowing how to
       | write text parsers is a useful CS skill.

         | hope afterwards it hasn't lost anything or changed the UI.

         | server. A number of Thunderbird filters move messages to their
         | folders and I backup them daily off site. If I stay weeks on
         | vacation, I check my current mail on my phone and that's it. If
         | it's vacation I don't care about old messages. Customers have a
         | copy of them anyway. I've been running like that for at least
         | 12 years, no need for IMAP. Well, maybe if I could access my
         | Thunderbird directory over IMAP, but it's not really important.
         | Running my own IMAP server would be such a small improvement
         | that anything else gets past it in the queue.
