SSL uses public-private key encryption to share session keys.  Typically
the server uses a key that is signed by a certificate authority (CA)
such as Verisign.  The public key for a commercial CA should be included
in the browser so it does all the verification for you.  The downside is
having to pay an extortionate amount for the CA to sign your key.
For a home server you can probably get away with a self-signed
certificate.  Your browser will warn you but you can still use the site
and the connection will be encrypted.

A proxy such as Squid will tunnel HTTPS connections.  By the nature of
the protocol a proxy cannot decrypt the connection so you are safe from
prying eyes.
As I said earlier, if you are setting up your own HTTPS server for
webmail a self-signed certificate is usually fine.  But if you are
setting up an e-commerce server then a commercial CA that is supported
by the main web browsers is essential.

Back to the original question regarding webmail/POP3.
Wifey probably shouldn't be using POP3 to access email from
cyber-cafes.  For one thing, cyber-cafes probably don't have a POP3
email client installed for the reasons:
1. that you have to configure it to download mail.  And cyber-cafes
typically tighten their machines up so users can't stuff them up.
2. You download mail (bad idea unless you really know how to remove it
from the system.
3. If you don't remember to remove your mail configuration the next guy
can view all your mail (and probably send mail as you also!)

Web mail is what you want.  All you need is a browser and no
configuration from the client end is required.  If you don't want to set
up a web mail server yourself, forward you mail to any of the many
webmail services available (e.g. Hotmail)  You'll probably find your ISP
has a web mail service available you can use.
