Our Review:

If you use Yahoo! mail then head straight for YPOPs! This allows you to download your Yahoo webmail from within a POP3 email client such as Outlook, Thunderbird or Eudora.

It's free, easy to set up using the instructions on the web site, and is simple to use. I use it on multiple Yahoo accounts and it works wonderfully. The most recent update is 0.9.7.3 which has fixed some memory corruptions although this was in 2009. The change log via the test forum can be found here forums.ypopsemail.com/ypops-windows-0-9-7-3-released-t3978.html.

Support forum and detailed configuration documentation are available from site. Tutorial: http://www.freepops.org/en/tutorial/index.shtml
