    Re: Limit internet mail

    you can't limit based on senders (at least I don't think so) - it's all or nothing.
    You also can't limit on specific external recipients, to the best of my knoweldge.

    What you COULD do, is if you wanted to block emails from everyone in your organisation to an entire domain (say, hotmail.com) Is you could create a send-connector that's specific to that domain, and just have it go nowhere.
    that way any email for hotmail.com would be routed via that connector.. but this would obviously be global, and not per-person.

      actually that's what I'm currently implementing, and I agree your opinion !!
      but my boss insists that he worked before with a system admin could do something like this !!!!
      I have no idea how to do this ??
      I though of the following scenario
      1- create a contact for the external e-mail (example: [email protected])
      2- create a user account and give him send to the gmail connector
      3- forward all that users mail to the contact I created in step no 1
      4- make users send mails to the internal user I created in step2

      but the result that users have no access to the gmail connector their mails couldn't be forwarded !!!!!!

        You may be able to use an SMTP connector to accomplish this. In Ex2003 the SMTP connector has the ability to receive or reject email from individuals that you specify. That said you would still need to modify the address spaces to your specification -with a higher cost- so that only certain email domains go through it.
        The problem you then have is this may prove very difficult to police and cumbersome to support. In addition you would need to scope additional SMTP connectors appropriately so that external mail flow to the internet is accepted or rejected depending on the email domain.
        Realistically speaking you don't want emails going into a black hole as that would break the RFC and users would never get an NDR if an email was never delivered.

          The closest you can get that works is to restrict the users to a specific domain.
          http://exchange.sembee.info/2003/smt...rnet-email.asp

          As far as I am aware there is no reliable technique that will work to restrict it to specific recipients.

          The method you have outlined I doubt whether it will work correctly.

            what if I upgrade to Exchange 2007 or 2010 ?
            can I then enable users to send emails to specific mail addresses (not whole domain) ?

              You may be able to use Transport rules to accomplish this with Ex2007 or 2010. That said the intended design of Exchange is to relay mail. If you want to be that granular then such a set up would be very difficult to support and often times hit and miss.

                I know what you mean ! but i'm working in a call center where agents are not supposed to send external emails except to some specific e-mails and that is the dilemma !!!

                  Transport rules will do the job, but it will become quite intensive to maintain. Restricting a few address to lots of people will be easy enough, but lots of addresses to lots of different people and it will become complex.

                  To paraphrase one of my fellow MVPs, you are seeking a technical solution to a behavioural problem.
