WEP/WPA/LEAP/802.1x and anything else which puts trust at the network 
level are close[1] to snake-oil - even if they actually worked as 
promised the only thing you get is a false sense of security because 
there's this assumption that the rest of the network is trustworthy. 
You get far more real security simply enabling the strong end-to-end 
crypto in the products you already use and you save a ton of money by 
not chasing the latest acronyms, too.

Check the "Use SSL" box in her email client, optionally switching to a 
competent ISP if this doesn't work.

We recently switch our POP/IMAP services over to a mandatory-SSL config 
and used the same approach other people in this thread have mentioned: 
3 months of warnings and then disabling the insecure versions. The only 
problems we had were a couple of people with antique Eudora installs 
who didn't want to upgrade. Other than that there was no grumbling 
thanks to an ettercap demonstration and the extremely low amount 
trouble/benefit ratio - we get far more whining each time we suggest 
that people install the latest Windows / Office security updates.

It's just not that hard to deploy SSL any more since almost any network 
client in common use includes SSL support by now - the biggest 
exception is file sharing and it's not like people are used to doing 
Windows networking over the internet - the worms have seen to that.

[1] I say close because it may be legally useful to say the network was 
restricted if you need to sue a spammer or something.
