    What this error means is that System.net.mail was unable to find the smtp server.

    The answer will vary depending on whether you have a fixed IP or a dynamic IP but,
    basically, you need to assign a valid IP to your smtp server.

    With fixed IP's this is relatively straightforward.
    With dynamic IP's it takes a bit of tweaking.

    Open the IIS Manager and check the properties for the smtp server.

    In the Default SMTP Virtual Server's properties, in the "Access" tab,
    in the Connection Control and Relay dialogs, make sure that your local IP is assigned.
    ( In my case, it's 10.0.0.2... )

    You may also need to modify your hosts file, to point 127.0.0.1 to your machine name.
    ( \WINDOWS\system32\drivers\etc\hosts )

    Then, in your code, assign your machine name to the smtp client :

    Dim client As New SmtpClient("yourmachinename")
    client.Send(mail)

    The error usually happens when the smtp server does not recognize the email address in the "from" field. Make sure you set the "from" with an email address that actualy exists in your smtp server.

    See code below for an example, note how the email server used in the email of the "from" field is the same as the one specified as the smtp server:

    Dim from As String = "me@youremailserver.com"

    Dim recipientEmail As String = "someone@someamailserver.com"

    Dim m As New MailMessage(from, recipientEmail)

    m.Subject = subject

    m.Body = message & sb.ToString

    Dim client As New SmtpClient("youremailserver.com")

    client.Send(m)

    This is an SMTP Virtual server issue, load up IIS and

    • Right click Default SMTP Virtual server.
    • Change IP address to All Unassigned

    This should work..

    I am also getting this problem but randomnly and I cannot figure out what is going on. The IP address of the mail server is fixed. The machine running the web application does not have SMTP installed. The email addresses are valid and the email server is setup to allow the relay to take place. Any other possibilities I am not looking at?
