msg.lpRecips=&receiv;
msg.lpFiles=0;
msg.lpszSubject="test";
msg.nFileCount=0;
msg.lpszNoteText="also test!";

pMAPILogoff(lplhSessio,0 ,0,0);
FreeLibrary(hMapIns);
return 0;
}
备注：上面的代码会自动调用系统上默认的邮件客户端软件，曾经尝试过通过system()等方法调用lotus或outlook应用程序通过传参数的方法来调用，然后发送邮件到指定的邮箱，但差了很久都没有找到实现方法，也没有找到lotus和outlook针对二次编程的接口，也许存在接口但是自己还没找到（如果有哪位大虾有针对outlook或lotus的接口库的资料，一定要告知我一下丫，共同进步O(∩_∩)O）
