I am attempting to send an email using ASP.NET 1.1's Mail.SmtpMail.Send()
method. My code contains all of the following:


Dim mailmsg As New Mail.MailMessage
Mail.SmtpMail.SmtpServer =
System.Configuration.ConfigurationSettings.AppSettings("smtpserver")
mailmsg.BodyFormat = Mail.MailFormat.Text

mailmsg.Subject = "My Subject"
mailmsg.Body = "My Body"
mailmsg.To = "(e-mail address removed);"
mailmsg.From = "My From Address"

Mail.SmtpMail.Send(mailmsg)


When I test the application, I recieve the following error:

Server Error in '/' Application.

one of the possible reason is your smtp server requires a login, contact
your system administrator about that. in .Net framework 1.1, you can use the
fields from the Mail object to add the attribute to pass the login
(username, password, smtpserver, smtpserver port number). Let me know if you
need the codes.

I concur.

The mail page/app is not able to connect to the smtp server.

Nathan should look into naming or availability issues.

I once got that message when I used "localhost" as my smtp server name.

When I created an smtp server virtual instance named for my machine's name,
everything worked, although I still had mail rejection problems ( mail servers don't
like receiving mail from single-name machines, instead of from properly-named mail servers ).

They went away when I used my domain name, instead of my machine name,
after creating an smtp virtual server named for my domain.

I removed the following two newsgroups from the address list :

microsoft.public.dotnet.framework.adonet
and
microsoft.public.dotnet.languages.vb

The problem is not related to a database nor to the VB language.

here you go:

objEmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserver",
yourSMTPServer);
objEmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpserverport",
25); //maybe a different port, 25 is the default
objEmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusing",
2);
objEmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate",
1);
objEmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendusername",
yourUsername);
objEmail.Fields.Add("http://schemas.microsoft.com/cdo/configuration/sendpassword",
yourPassword);
