Therefore this is a LOOPHOLE that our users use to send UNATHORISED INTERNET mail, now since they don’t have OFFICIAL Internet addresses X.400 is used as the ADDRESSING mechanism e.g. ‘IMCEAEX-_O=WIDGET_OU=ROMAN_CN=RECIPIENTS_CN=RONELL@widget.com’
This is the address that the recipient of this message that is outside our organisation receives and all they have to do is to reply to this message OR copy this ADDRESS into their address book and then they can send the UNATHORISED user INTERNET mail. So what I’m trying to do is to prevent UNATHORISED users in our site from using this LOOPHOLE. I’ve managed to prevent them from sending INTERNET mail now by asking the network administrator of the other site to REJECT all requests from people in our site to use the IMC connector but I can’t find a way of preventing EXTERNAL users from sending these users mail by using the X.400 addressing.
Does anyone know how I can prevent mail from entering our system when outside users use the X.400 addressing mech
