Help Needed with SMTP mail in ASP.Net

[Robert Hanson]

Hi All,

I am getting an error Could not access 'CDO.Message' object when I run
the SmtpMail.Send(msg) line as shown below:

Dim msg As MailMessage = New MailMessage
msg.To = strRecipientEmailAddressList
msg.From = strSenderEmailAddress
msg.Subject = "SimpleERouting AutoNotify Message"
msg.Body = "SimpleERouting Number " + strErouting + "
AutoNotify Message From " + strCreator
SmtpMail.SmtpServer = "localhost"
SmtpMail.Send(msg)

This is on my development computer using IIS5.0

Please help!!

Thanks,

Hello David,

I did try that first and I received the same error. Is there something
in particular is IIS5.0 settings that could cause this?

Thanks for your help!

Hello Robert,

You should check the exception that the SmptMail.Send throws. Look through the .InnerException chain until you arrive on a
COMExeption; this one will include the error message thrown by the SMTP server (you'll probably want to send mails with a
"from" account that is not in the domain of your SMTP server; this leads to a 500 error from SMTP, which in turn pops up as a
"cannot access CDO.Message" in your app).

Please also make sure the SMTPSVC service was started, and you have granted relay permissions to 127.0.0.1, etc.

By the way, ASP.NET, as we know, runs as the under-privileged user "ASPNET" on the local machine. This user does not
have privileges to access the network an create sockets (such as the socket necessary to connect to the SMTP server to
send the mail).

It DOES, however, have privileges to create a socket to the local machine (127.0.0.1 localhost).

So if you plan on using SmtpMail from an ASP.NET app, you MUST use your local SMTP Service, and not an external one.

Thanks.
