YahooPOPs! is an open-source initiative to provide free POP3 access to your Yahoo! Mail account. It emulates a POP3 server and enables popular email clients like Outlook, Netscape, Eudora, Mozilla, Calypso, etc., to download email from Yahoo! accounts.

YahooPops acts like a gateway. It provides a POP3 server interface at one end to talk to email clients and an HTTP client (browser) interface at the other which allows it to talk to Yahoo!

Where to place these files:
• use terminal to place ypops and ypops.bin to /usr/local/bin
(since Finder cannot access to that directory.)
• launch Terminal.app in the /Applications/Utilities
• cd [path to this un-zipped folder]
(you can drag the folder's icon into the terminal window to get the path)
(so it looks like cd /Users/JohnDoe/Documents/download/yahoopops_mac)
• sudo chmod u+x ypops
• sudo chmod u+x ypops.bin
• sudo cp ypops /usr/local/bin/
• sudo cp ypops.bin /usr/local/bin/
• use terminal or Finder to place ypopsrc to your home directory
• cp ypopsrc ~/

Use TextEdit (or SubEthaEdit, recommended) to edit the content of ypopsrc in your home directory to match your configuration (in particular, if you have proxy server to handle external connection...). Otherwise, the setting in the ypopsrc should be OK for most users:
• it will flag those fetched mails as 'read' in yahoo;
• it will empty the trash folder each time it visit yahoo;
• it will fetch 10 mails in each visit. (it seems that yahoo will lock the mail account temporarily if it sees the large amount of mail download activity in a short interval of time. So, don't set this number too large. Also, large number for this setting may make yahoopops delay the response back to Mail.app, which will think the localhost mail server (yahoopops) is defunct.)
