一个用c++写Send Mail程序时遇到关于MIME的问题

ansonlu

本人用Socket写Send Mail程序时不知道如何写MIME的格式.
如下: (用OUTLOOK得到的邮件内容)
From: "163" <[email protected]>
To: <[email protected]>
Subject: wavfile
Date: Sun, 20 Apr 2003 10:13:44 +0800
MIME-Version: 1.0
Content-Type: multipart/mixed;
        boundary="----=_NextPart_000_0009_01C30725.86786F50"      (分界标志)
X-Priority: 3
X-MSMail-Priority: Normal
X-Mailer: Microsoft Outlook Express 6.00.2800.1106
X-MimeOLE: Produced By Microsoft MimeOLE V6.00.2800.1106

This is a multi-part message in MIME format.

------=_NextPart_000_0009_01C30725.86786F50
Content-Type: multipart/alternative;
        boundary="----=_NextPart_001_000A_01C30725.867B7C90"


------=_NextPart_001_000A_01C30725.867B7C90
Content-Type: text/plain;
        charset="gb2312"
Content-Transfer-Encoding: base64
