Hotmail 的 account 已经加上了，但Yahoo的尽管加上了但好像没连上，既不可以显示收件箱的信。尽管server的类型都试过（POP3, IMAP, HTTP),（其实本人根本不懂这三个到底有啥区别），但还是不行。望高手指点。多谢了！

Yahoo's POP3 support is open only to paid users.

POP3: Post Office Protocol v3, used to download e-mails.
IMAP: Internal Mail Access Protocol, a replacement for POP3 with more advanced mailbox management functionality.
HTTP: Web access...

If you do want to use POP for your Yahoo account, you may check out YahooPOPs, which is a freeware local POP to HTTP proxy for your Yahoo! account.

免费的，关于yahoo.com的邮箱嘛，可以试一下foxmail

YPOPs! is an application that provides POP3 access to Yahoo! Mail. It is available on the Windows, Linux, Solaris and Mac platforms.

Yahoo! Mail disabled free access to its POP3 service on 24th April, 2002. This application emulates a POP3 server and enables popular email clients like Outlook, Netscape, Eudora, Mozilla, etc., to download email from Yahoo! accounts. We do not go against the license agreements of Yahoo! Mail. This application is completely legitimate and well within the realms of legal software.

How do we do it you ask? Well, this application is more 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

只要设好pop和smtp就可以。

pop.yahoo.com.sg
smtp.yahoo.com.sg
