Re: Mail sent through IIS virtual SMTP server not arriving

It looks like that a lot of people have this problem, i.e., no
exception is thrown, but messages got packed up under
Inetpub/mailroot/Queue/ and never get sent. However, there does not
seem to have a solution so far. I googled around, only see people
asking for help, no one has really offered a solution to this problem.

At the following link, Leszek did say the problem was solved. But
she/he did not go into detail about her solution. E.g., How to set up
a real sender address on the SMTP virtual server? She/He did not
explain it.

Also, it looks like that she/he was using smarthost, which to my
understanding, is sending mail through a remote SMTP server provided by
some ISP. That would be a different story from what I am trying to
solve.

Here is that post:

Thank you very much.
There were several problems with my IIS configuration (smart host, smtp
server name etc). Moreover it turned out that I needed to set up a real
sender address (From: field) to enforce the IIS to send emails. Strange
but now it works perfectly.

Youi'll find sample code for changing the port number under system.web.amil here :

http://systemwebmail.com/faq/2.9.aspx

Essentially :

MailMessage mail = new MailMessage();
mail.To = "me@xxxxxxxxxxxxx";
mail.From = "you@xxxxxxxxxxxxxxx";
mail.Subject = "this is a test email.";
mail.Body = "Some text goes here";
mail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport";, "your port number");
SmtpMail.SmtpServer = "YourSmtpServer";
SmtpMail.Send(mail);

There's VB.NET sample code in the same page.

Keep that systemwebmail link handy.
All the info you need to solve web mail problems under .Net 1.1 is there.

There's specific answers for both the "Could not access 'CDO.Message' object"
and "The transport failed to connect to the server" exceptions which you reported.

Hi, Juan,

Thanks a lot. Unfortunately, it looks like that the SmtpClient is only
available with .Net framework 2.0

I am using .Net Framework 1.1

I know nothing about 2.0 at this point of time. Is there any way to go
around this?

re:

Too bad that the .Net SmtpMail class does not let us set the port number.

But it does allow you to do that :

static void ChangePort()
{
//create the mail message
MailMessage mail = new MailMessage();

//set the addresses
mail.From = new MailAddress("me@xxxxxxxxxxxxx");
mail.To.Add("you@xxxxxxxxxxxxxxx");

//set the content
mail.Subject = "This is an email";
mail.Body = "this is the body content of the email.";

//send the message
SmtpClient smtp = new SmtpClient("127.0.0.1");

//to change the port (default is 25), we set the port property
smtp.Port = 587;
smtp.Send(mail);
}

Of course, for that to work you must set IIS's SMTP server
to the same port you set in your code. You can use any TCP port.

To do that, view the Properties of the Default SMTP Server;
click the "Delivery" tab; click the "Outbound Connections" button;
and set the port number you want in the "Tcp port" box.

That will get around your ISP's blockage of port 25.

Hi, Juan,

Now I am having the typical "Could not access 'CDO.Message' object" and
"The transport failed to connect to the server" exceptions.
