Free POP Mail...

I just wondering how many free pop mail servers in the world! I think it's nice to search and posting here in my blog.
And who ever need some information regarding free pop mail, just can easily look thru here.
Starting with Hotpop mail Easy setup and works ok .Note that the free account has a 500 KB size limit for email messages. POP3: pop.hotpop.com, 
SMTP: mail.hotpop.com.
GMX Mail They're only using German Language to sign up ( a little bit confusing for me..) and Their signup forms do not allow American postal addresses anymore, but accepts any address from Germany, Austria or Switzerland.
Some people said that yahoo.com.sg also can provide free Pop mail, as long as you sign up at their server 'yahoo.com.sg'.
The best 1 GB email Gmail from Google give you unlimited email size that ever had! unfortunately they're already close if you go to gmail website for sign up. But still you can get it! how? you can get it from your friend that previously already registered with gmail. Ask them to invite you, each person had 4 or 5 invitation leter.
I believe there are still free pop mail outside that I don't know where? But maybe you guys can give me a clue whereabout the rest of free pop mail?
Thanks.
