You might want to take a peek at <A target="_blank" HREF=http://www.operamail.com>http://www.operamail.com</A>
I love the Opera browser, so got myself an operamail account too. I don't use it much.. mostly as a throw-away account. You know, when some nosy company insists on you giving them an email address, you give them the throw-away address. When the spam gets overwhelming, you just abandon the account and create a new one.
Anyway, I believe Operamail lets you have POP mail retrieval.
HTH,
