这是本人在Windows mobile上开发邮件系统时，封装出来的邮件内容解析的类，供大家参考
目前可以解析大部分的邮件，测试邮件基本上是常用的邮件客户端或一些Webmail系统上发出。
如果任何问题请留言告之，谢谢...
以下代码是邮件解析核心代码部分
BOOL CXNParseMailMsg::ParseBody()

char
szTmp[
512

""

GetHeaderItem(szTmp, MAIL_MESSAGE_CONTENT_TYPE, strlen(MAIL_MESSAGE_CONTENT_TYPE));

p1
=
strstr(szTmp, MAIL_MESSAGE_CONTENT_TYPE_BOUNDARY);
if
(p1)
{
int
nPos
=
p1
-
szTmp
+
strlen(MAIL_MESSAGE_CONTENT_TYPE_BOUNDARY)
+
1
;
char
