OnAcceptMessage(oClient as hMailServer.Client, oMessage as hMailServer.Message)

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 OnAcceptMessage(oClient, oMessage)

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

Reject message larger than a specific size.

VB-script:

Sub OnAcceptMessage(oClient, oMessage)       

   If oMessage.Size > 10 Then          
      ' Reject the message since it's larger          
      ' than 10 kb.          
      Result.Message = "This message is too large"
      Result.Value = 2
   Else
      ' Accept the message          
      Result.Value = 0     
   End If     

End Sub  

Notes

• OnAcceptMessage is executed before hMailServer has accepted the email message and before it has been saved in the database. This means that you cannot access the ID of the message in this event.
