Before you begin:
This code returns number of incoming email messages waiting on a POP3 server without opening your default email client (Outlook Express, GoupWise, Eudora etc.).

Also it contains basic GetMsg and GetMsgTop methods being good enough for reading those messages.

Note that even after being read all messages stay on your server (unless you decide to issue the DELE command), so they will be available for retrieving in your regular email program.

In the beginning part of the code replace connection attributes with valid ones from your email account. This is where you can find them in Microsoft Outlook Express:

    My comment:
    A screen output will be similar to the following:

    Connecting to pop3.fastmail.com, 192.168.0.1 ...
    +OK POP3 server ready.

    >> USER UncleJoe
    +OK Password required.

    >> PASS checkmail
    +OK logged in.

    >> STAT 5 67312

    >> QUIT
    +OK POP3 server signing off.


    "STAT 5" means that there is 5 messages waiting.
