The specified protocol is unknown. <- Help.

Jerry Camel

Let's try this again... I think I sent half a message before.

Things were working just fine and I'm not sure what changed. The code is pretty simple. But now I can't send a message anymore. I get this exception:

System.Web.HttpException: Could not access 'CDO.Message' object. ---> System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x800C000D): The specified protocol is unknown.

Code:

Dim msg As New MailMessage()
Dim attach As New MailAttachment(resultsFileName)
Dim i As Integer

msg.Attachments.Add(attach)
msg.From = "(e-mail address removed)"
msg.Subject = Application.ProductName & ": " & Now
SmtpMail.SmtpServer = smtpServer
For i = emailAddresses.GetLowerBound(0) To emailAddresses.GetUpperBound(0)
msg.To = emailAddresses(i)
SmtpMail.Send(msg)
Next i

I've searched and serarched and while I can find many references to the CDO.Message issue, none address the "Protocol is unknown" part.

Any help is truly appreciated...

Jerry
