Although many people love Yahoo! Mail for its sleek interface and rich set of features, the fact that it doesn't allow POP3 access to its mail servers (unless ones has a paid subscription) has always been a problem for many. This is where YPOPs! comes in. YPOPs! runs in the background of your computer and simulates POP access so you can download your Yahoo email to you desktop email client such as Microsoft Outlook 2007, Windows Mail or Mozilla Thunderbird.
