Re: Mail sent through IIS virtual SMTP server not arriving

It does look like your ISP is blocking port 25.
Read my previous post and test using a different port.

Hi, Juan,

I got the smtp server log as follows. The code is 250, which according
to what you said meant that the mail has been sent successfully. But
the mail never arrived.

Under Inetpub/mailroot/Queue, the email messages are all sleeping
there.

This is one of them:

I just checked the logfile like you instructed.

You checked the HTTP log ( \%windir%\system32\LogFiles\W3SVC1 ),
but not the SMTP log.

The line :
18:25:16 130.126.83.20 POST /sendmail/vmailman.aspx 200

tells you that you POSTed to sendmail.
It doesn't tell you what the smtp server did with that POST.

Please check the \%windir%\system32\LogFiles\smtpsvc1 logs.
( and send the last 8 lines of today's log... )

Hi, Juan,

Thanks, I just checked the logfile like you instructed. And here is a
part of it. You will see GET /favicon.ico 404 in the log. And here is
a dicussion of it:

http://www.webmasterworld.com/forum39/104.htm

And for the definition of the HTTP code 200, see here:

http://64.233.179.104/search?q=cache:7vjrLlciKIIJ:www.w3.org/Protocols/rfc2616/rfc2616-sec10.html+http+code+200&hl=en&gl=us&ct=clnk&cd=1

So, given the log below, could you diagnose what problem it is?

Thanks.

The way to find out, for sure, is to turn on smtp logging.

To turn on logging, open the IIS Manager,
and select the Default SMTP Server's properties.

You'll see the option for turning it on and for selecting the type of log.
Clicking the Properties and then the Advanced button lets you select the fields to log.

The log, by default, will be stored at \windowsdir\system32\LogFiles\smtpsvc1

You should see entries like :
2006-03-01 14:58:32 111.111.111.111 smtpservername SMTPSVC1 0 HELO 250 33 - -
2006-03-01 14:58:32 111.111.111.111 smtpservername SMTPSVC1 0 MAIL 250 47 - -
2006-03-01 14:58:32 111.111.111.111 smtpservername SMTPSVC1 0 RCPT 250 34 - -
2006-03-01 14:58:32 111.111.111.111 smtpservername SMTPSVC1 0 DATA 250 125 - -

If the mail packet was successfully sent, the success code is 250.

Any other code means some sort of problem
which prevented the mail from getting sent.

Check that...and let us know what you see after you attempt to send mail.

Thanks, Bruce.

I know that I won't have any problem for my application in sending and
receiving email if I simply use the SMTP server of my ISP. I tried it,
and it worked perfectly fine. And in this case, I don't have do
anything about the virtual SMTP server on my IIS 5.1.

But, I am trying to test if I can send email in my web application
through the IIS virtual SMTP server only.

So if I end up having to forward to my ISP's SMTP server, it'll beat my
objective, plus, I could have just used my ISP's SMTP service.

So, any idea about why I am not receiving the mail "sent" from the
virtual SMTP? By quoting "sent", I meant that at least it looks like
to have been sent.

require the from match authenication?

I've set up the virtual smtp server on my IIS 5.1 like so:

1. Assign IP address to "All Unassigned", and listen to port 25.
2. Access Connection granted to "127.0.0.1".
3. Relay only allow "127.0.0.1".
4. Authentication: "Anonymous access" only.
5. Outbound connection listen to TCP 25.

Besides,

6. I've opened up port 25 in my Linksys WRT45G wireless router.
7. I've made port 25 an exception in my WinXP Pro built-in firewall.
8. Unblocked port 25 in McAfee 8.0 enterprise edition.

I used the following code, and

Response.Write("Your E-mail has been sent sucessfully - Thank You")

is executed and I don't see any exception.

However, the mail never arrived!

So, what's the problem?

Is it possible to configure the virtual SMTP server to listen to a
non-standard port for just sending email? I heard that my ISP SBC DSL
blocks port 25. If this is possible, how to let it listen to a
different port?

***** The code I use ***********

<%@ Page Language="VB" Debug="true" %>
<%@ Import Namespace="System.Web.Mail" %>

<script runat="server">

Sub btnSubmit_Click(sender as object, e as EventArgs)
If Page.IsValid Then
' Create a new blank MailMessage
Dim mailMessage As MailMessage = new MailMessage ()
mailMessage.From = txtFrom.Text
mailMessage.To = txtTo.Text
mailMessage.Cc = txtCc.Text
mailMessage.Subject = "Test SMTP Message Send using port"
mailMessage.Body = txtName.Text & ", " &txtComments.Text
SmtpMail.SmtpServer = "127.0.0.1"

Try
SmtpMail.Send(mailMessage)
Response.Write("Your E-mail has been sent sucessfully - Thank You")
Catch ex As Exception
Response.Write(("The following exception occurred: " +
ex.ToString()))
'check the InnerException
While Not (ex.InnerException Is Nothing)
Response.Write("--------------------------------")
Response.Write(("The following InnerException reported: "
+ ex.InnerException.ToString()))
ex = ex.InnerException
End While
End Try
End If
End Sub
</script>
