number is required. According to real life, it's a damn sight easier just
to run stunnel and get it to relay on to pop3 bound to 127.0.0.1. QPopper
is the only pop3 daemon I could find on a quick search that explicitly
supports TLS, and I'm not overly sure how well it's supported client side.
pop3s I know for sure is pretty well supported, even by Microsoft clients.
Plus pop3s has the advantage (for high throughput sites) that you can
separate the SSL processing from the POP3 processing onto separate
