看过Borland的VCLScanner吗？由源代码的，里面有关于向定点邮箱发送邮件的代码，去下载一个看一看吧。Top

{ Send the Mail, silent or verbose:
Verbose means in Express a Mail is composed and shown as setup.
In non-Express versions we show the Login-Dialog for a new
session and after we have choosen the profile to use, the
composed email is shown before sending
Silent does currently not work for non-Express version. We have
no Session, no Login Dialog so the system refuses to compose a
new email. In Express Versions the email is sent in the
background.
}
if FShowDialog then
MError := MapiSendMail(0, AppHandle, MapiMessage, MAPI_DIALOG or MAPI_LOGON_UI or MAPI_NEW_SESSION, 0)
else
MError := MapiSendMail(0, AppHandle, MapiMessage, 0, 0);
{ Now we have to process the error messages. There are some
defined in the MAPI unit please take a look at the unit to get
familiar with it.
I decided to handle USER_ABORT and SUCCESS as special and leave
the rest to fire the "new" error event defined at the top (as
generic error)
Not treated as special:
MAPI_E_AMBIGUOUS_RECIPIENT,
MAPI_E_ATTACHMENT_NOT_FOUND,
MAPI_E_ATTACHMENT_OPEN_FAILURE,
MAPI_E_BAD_RECIPTYPE,
MAPI_E_FAILURE,
MAPI_E_INSUFFICIENT_MEMORY,
MAPI_E_LOGIN_FAILURE,
MAPI_E_TEXT_TOO_LARGE,
MAPI_E_TOO_MANY_FILES,
MAPI_E_TOO_MANY_RECIPIENTS,
MAPI_E_UNKNOWN_RECIPIENT:
}
case MError of
MAPI_E_USER_ABORT:
begin
if Assigned(FOnUserAbort) then
FOnUserAbort(Self);

SUCCESS_SUCCESS:
begin
if Assigned(FOnSuccess) then
FOnSuccess(Self);
end
else begin
if Assigned(FOnMapiError) then
FOnMapiError(Self, MError);
end;
end;
finally
{ Finally we do the cleanups, the message should be on its way }

SMTP安全认证的邮件发送程序:
c:ehlo hostname
s:250-smtp.263.net
250-pipelining
250-size 10240000
250-etrn
250-auth login
250-8bitmime
以上是与邮件服务器连接，即nmsmtp1->connect,以下是连接后的验证：
c:auth login
s:334VXNlcm5hbWU6（username:)
c:b(你的用户名转换成base64码）
s:334UGFzc3dvcmQ6(password:)
c:x（你的密码转换成base64码）
nmsmtp有个transaction方法,在onconnect事件中加入验证过程，
nmsmtp1->transaction("auth login"),返回值是334表示通过，可以继续下面的
nmsmtp1->transaction（你的用户名转换成base64码）
nmsmtp1->transaction(你的密码转换成base64码)
如果返回235表示验证成功，你就可以发邮件了
