MailMessage Problem

[Wayne Wengert]

Using the code below, I am trying to send an email from an ASP.NET 2.0 page
but I get the error " The specified string is not in the form required for
an e-mail address." when the "Dim Mailmsg..." line is executed. Since I
haven't defined the from/to yet, I don't understand what it wants? Any
insight on what causes this?


=========================================
Dim obj As System.Net.Mail.SmtpClient = New System.Net.Mail.SmtpClient
Dim Mailmsg As New System.Net.Mail.MailMessage
Mailmsg.To.Clear()
Mailmsg.To.Add(New System.Net.Mail.MailAddress("To Name
<[email protected]>")
Mailmsg.From = New System.Net.Mail.MailAddress("From Name
<[email protected]>")
Mailmsg.Subject = "(subject text)"
Try
Mailmsg.Body = "(message text here)"
obj.Send(Mailmsg)
Catch ex As Exception
Response.Write("Error: " & ex.ToString())
End Try
=========================================

re:

Actually, you *have* defined it, as :

Mailmsg.To.Add(New System.Net.Mail.MailAddress("To Name <[email protected]>")
Mailmsg.From = New System.Net.Mail.MailAddress("From Name <[email protected]>")

It's expecting a mail address in the form :

new MailAddress("(e-mail address removed)", "Some Name");

Try :

Mailmsg.To.Add(New System.Net.Mail.MailAddress("(e-mail address removed)", "To Name")
Mailmsg.From = New System.Net.Mail.MailAddress("(e-mail address removed)", "From Name")

I hsould have added...

See http://msdn2.microsoft.com/en-us/library/system.net.mail.mailaddress.aspx
and http://msdn2.microsoft.com/en-us/library/1s17zfkf(VS.80).aspx

I'm confused. The error occurs on the "Dim Mailmsg..." before the To and
From addresses are set?

Sure, that's standard OOP procedure.

When you call an object, all of its components are called, too.

Sloan;

Thanks for that response - You pointed me in what I am sure is the right
direction. I am trying to get the web.config settings right for my
environment (Comcast). It seems that comcast does not require authorization
but there must be something else I overlooked as I am getting the following
error;

Mailbox unavailable. The server response was: [PERMFAIL] comcast.net
requires valid sender domain

I am not sure exactly what it wants - I did try my comcast login and PW but
that had no effect?

I got it working. That last problem was caused by my use of a domain that
had not been activated yet in the From address.
