sendusing in smtp why?

Hi,
I got Error "The "SendUsing" configuration value is invalid." while
using following code.
MailMessage sendinfo= new MailMessage();
sendinfo.BodyFo rmat=MailFormat .Html;
sendinfo.Body=" bodyvalue";
sendinfo.To="em ailadd@mydomain ";
sendinfo.From=" emailadd@mydoma in";
sendinfo.Subjec t="Preview Newsletter";
SmtpMail.Send(s endinfo);

Therefore, I added a line.
SmtpMail.SmtpSe rver="localhost ";
It then gave me error "The server rejected one or more recipient
addresses server response was: 550 5.7.1 Unable to relay for
myemailaddress"

I saw a few message threads saying that the email address has to be in
same domain to get this to run and it already is.

I have tested this code in 2 servers. It works at one even without
even the smtpserver specifiation and it doesn't work on the other
server no matter what I try. I have tried several methods
e.g.CDO.Message () and non seem to work on this server. It has to be
something with configuration. I dont understand. I have spent a lot of
time on it.
Any suggestion will be great.
Thanks
Dee

I'm new to .NET and just trying a few things out, like emailing. I created a form in Visual Studio .Net to input some information for generating an email and I'm getting the following error when it executes both on my server or on the server of the .NET service provider. I'm obviously missing something very basic and I'm hoping one of you can point out my error. Thank you for your assistance. Brian

This is really a lame error. I've spent two days scouring the internet for a proper solution to my problem. My issue is that I have an ASP.NET website using a VB.NET COM object to send emails (code below). This sporadically works to send emails, but mostly gets the error mentioned. Once an email does go out then the server sends emails fine until IIS is reset. I found this "SendUsing Configuration is Invalid" error attempting to be...

Can someone show me what the correct code snippet would be? Here is my code: ...

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
