SMTP Authentication With The MailMessage Class

Printer Friendly Version

Many people think that you cannot authenticate a SMTP server using the System.Web.Mail.MailMessage class and opt paying for an alternative. Well heres a solution that may save you some money. Dim Msg As New System.Web.Mail.MailMessage Msg.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserver") = "smtpserver" Msg.Fields("http://schemas.microsoft.com/cdo/configuration/smtpserverport") = 25 Msg.Fields("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 Msg.Fields("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = 1 Msg.Fields("http://schemas.microsoft.com/cdo/configuration/sendusername") = "username" Msg.Fields("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password" Msg.To = "dst@addr.net" Msg.From = "src@addr.net" Msg.Subject = "Subject" Msg.Body = "Message" System.Web.Mail.SmtpMail.SmtpServer = "smtpserver" System.Web.Mail.SmtpMail.Send(Msg) This example is for a remote server, to authenticate the localhost you do not need to set the smtpserver field or the smtpserverport field. Just change the sendusing field to 1 & SmtpMail.SmtpServer to localhost For more things you can do with the MailMessage Class check out MSDN at http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cdosys/html/_cdosys_schema_configuration.asp
