in the inc_mail.asp file, there is section that looks like this:
case "cdosys"
Set iConf = Server.CreateObject ("CDO.Configuration")
Set Flds = iConf.Fields
'Set and update fields properties
Flds("http://schemas.microsoft.com/cdo/configuration/sendusing") = 2 'cdoSendUsingPort
Flds("http://schemas.microsoft.com/cdo/configuration/smtpserver") = strMailServer
'Flds("http://schemas.microsoft.com/cdo/configuration/smtpauthenticate") = cdoBasic
'Flds("http://schemas.microsoft.com/cdo/configuration/sendusername") = "username"
'Flds("http://schemas.microsoft.com/cdo/configuration/sendpassword") = "password"
Flds.Update
Set objNewMail = Server.CreateObject("CDO.Message")
Set objNewMail.Configuration = iConf
'Format and send message
Err.Clear
objNewMail.To = strRecipients
objNewMail.From = strSender
objNewMail.Subject = strSubject
objNewMail.TextBody = strMessage
On Error Resume Next
objNewMail.Send
If Err <> 0 Then
Err_Msg = Err_Msg & "<li>Your request was not sent due to the following error: " & Err.Description & "</li>"
End if
you just need to edit the file, and uncomment (remove the ' from in front of the line) the 3 lines that start with Flds and then change username & password to the username/password you use to login to the SMTP server you specify in the Mail Configuration. Using the IP address should be fine.
