Webmail

Webmail實現源理，有三種。1、使用POP、IMAP　Socket實現，2、通過直接訪問物理檔案實現，3、使用語言的開發包API實現。

基于IMAP,POP的webmail系統

SquirrelMail

SquirrelMail是使用PHP開發的webmail基于IMAP協議,對postfix,qmail....支持很好。

安裝配置SquirrelMail

  1. 下載SquirrelMail，解包後複製到Apache目錄下

    [root@linuxas3 src]# wget http://heanet.dl.sourceforge.net/sourceforge/squirrelmail/squirrelmail-1.5.0.tar.gz

---------------------------------------------------------
While we have been building SquirrelMail, we have discovered some
preferences that work better with some servers that don't work so
well with others.  If you select your IMAP server, this option will
set some pre-defined settings for that server.

Please note that you will still need to go through and make sure
everything is correct.  This does not change everything.  There are
only a few settings that this will change.

Please select your IMAP server:
    cyrus      = Cyrus IMAP server
    uw         = University of Washington's IMAP server
    exchange   = Microsoft Exchange IMAP server
    courier    = Courier IMAP server
    macosx     = Mac OS X Mailserver
    mercury32  = Mercury/32
