Plz help me to correct my code to send E-mail as NT service .

I tried to send e-mail as NT service but i could not send it. the
Mapilogon function fails to logon in NT service.

But It works well as an Standalone application.


here is my code for only sending mail.....


MapiFileDesc
file={0,MAPI_OLE_STATIC,0,"D:\\MSDN.doc","MSDN.doc",".Doc"};


MapiRecipDesc recipient ={0, MAPI_TO,"NT Service test mail",email,0,
NULL};


MapiMessage message ={0,(char *)Name,"NT Service testl" , NULL,NULL ,
NULL , 0 , NULL , 1 , &recipient , 1 , &file};


LHANDLE lhSession;


HMODULE hMAPILib;


hMAPILib = LoadLibrary("MAPI32.DLL");


lpfnMAPILogon =(LPMAPILOGON)GetProcAddress(hMAPILib, "MAPILogon");


lpfnMAPISendMail =(LPMAPISENDMAIL)GetProcAddress(hMAPILib,
"MAPISendMail");


lpfnMAPILogoff =(LPMAPILOGOFF)GetProcAddress(hMAPILib, "MAPILogoff");


ULONG ln;


ln=(*lpfnMAPILogon)(0, "SB","sb", MAPI_NEW_SESSION , 0,&lhSession);


if(ln==SUCCESS_SUCCESS)
MessageBox(NULL,"logon","NT Service",MB_OK);
else
MessageBox(NULL,"not logon","NT Service",MB_OK);


(*lpfnMAPISendMail)(lhSession, 0, &message, 0, 0);


(*lpfnMAPILogoff)(lhSession, 0, 0, 0);


MessageBox(NULL,"Message sent","sent",MB_OK);


FreeLibrary(hMAPILib);


When i run as NT service the Messagebox is displayed which shows "not
logon".
But it works well as standalone application..

Try using CDO-NTS objects instead of MAPI.

Right. MAPI sends e-mail using the current e-mail application of the
currently logged-on user. Services do not have access to the currently
logged-in user. They run in a separate environment.

You could try using SMTP, or you can investigate using impersonation.
