有没有人用2000 server 下的SMTP服务

[zjlxl]

我准备写一个邮件群发的小程序，想用2000 server下的SMTP服务，做邮件发送服务器，那位这样大侠用过？

HMODULE hMod = LoadLibrary("MAPI32.DLL");

if (hMod == NULL) //加载动态库失败
{
AfxMessageBox(AFX_IDP_FAILED_MAPI_LOAD);
return;
}

//获取发送邮件的函数地址
ULONG (PASCAL *lpfnSendMail)(ULONG, ULONG, MapiMessage*, FLAGS, ULONG);
(FARPROC&)lpfnSendMail = GetProcAddress(hMod, "MAPISendMail");

if (lpfnSendMail == NULL)
{
AfxMessageBox(AFX_IDP_INVALID_MAPI_DLL);
return;
}

int nFileCount = m_list.GetCount(); //有多少个附件需要发送

//分配内存保存附件信息 不能使用静态数组，因为不知道要发送附件的个数
MapiFileDesc* pFileDesc = (MapiFileDesc*)malloc(sizeof(MapiFileDesc) * nFileCount);
memset(pFileDesc,0,sizeof(MapiFileDesc) * nFileCount);

//分配内存保存附件文件路径
TCHAR* pTchPath = (TCHAR*)malloc(MAX_PATH * nFileCount);

CString szText;
for(int i = 0;i < nFileCount;i++)
{
TCHAR* p = pTchPath + MAX_PATH * i;
m_list.GetText(i,szText);
strcpy(p,szText);

(pFileDesc + i)->nPosition = (ULONG)-1;
(pFileDesc + i)->lpszPathName = p;
(pFileDesc + i)->lpszFileName = p;
}

//收件人结构信息
MapiRecipDesc recip;
memset(&recip,0,sizeof(MapiRecipDesc));
recip.lpszAddress = m_szEmailMAPI.GetBuffer(0);
recip.ulRecipClass = MAPI_TO;

//邮件结构信息
MapiMessage message;
memset(&message, 0, sizeof(message));
message.nFileCount = nFileCount; //文件个数
message.lpFiles = pFileDesc; //文件信息
message.nRecipCount = 1; //收件人个数
message.lpRecips = &recip; //收件人
message.lpszSubject = m_szSubject.GetBuffer(0); //主题
message.lpszNoteText= m_szText.GetBuffer(0); //正文内容

//保存本程序窗口指针，因为发完邮件后要返回本程序的窗口
CWnd* pParentWnd = CWnd::GetSafeOwner(NULL, NULL);

//发送邮件
int nError = lpfnSendMail(0, 0,
&message, MAPI_LOGON_UI|MAPI_DIALOG, 0);

if (nError != SUCCESS_SUCCESS && nError != MAPI_USER_ABORT
&& nError != MAPI_E_LOGIN_FAILURE)
{
AfxMessageBox(AFX_IDP_FAILED_MAPI_SEND);
}

//返回程序
pParentWnd->SetActiveWindow();

//不要忘了释放分配的内存
free(pFileDesc);
free(pTchPath);
FreeLibrary(hMod);
