Examples

Require authentication for local senders

The built-in SMTP authentication functionality checks only the sender address to determine whether SMTP authentication is required. Often, you want to check sender address as well. The following script makes hMailServer require authentication, if the senders address contains @example.com.

VB-script:

Sub OnSMTPData(oClient, oMessage)

   If (InStr(1, oMessage.FromAddress, "@example.com", 1) > 0) Then
      If (oClient.Username = "") Then
         Result.Message = "You must be authenticated to send from local domain."
         Result.Value = 2
      End If
   End If

End Sub
