Here is the code I am trying to use to send an email message from a web form<BR> <BR> Dim mailMessage As New Mail.MailMessage()<BR><BR> mailMessage.From = "email@example.com"<BR> mailMessage.To = "firstname.lastname@example.org"<BR> mailMessage.Subject = "test message"<BR> mailMessage.Body = "test message body"<BR> Mail.SmtpMail.SmtpServer = ""<BR> Mail.SmtpMail.Send(mailMessage)<BR><BR>I keep getting the error - The "SendUsing" configuration value is invalid <BR><BR>I'm new to this so I'm not sure if I need to configure anything. I have the SMTP service on my local machine and it's running (I don't know if that matters or not). This local machine is not used as a mail server though. There is a network mail server elsewhere in the building. I tried to enter that servers name for SmtpMAil.SmtpServer but got the error - The transport failed to connect to the server.<BR><BR>Now I have no idea what to try. <BR><BR>Thanks for any help!
