Block external email for set of users - they are not all members of a distribution group

    Question

  • Hello

    I would like to setup a transport rule to block external email for a set of users. i.e. those users cannot send email externally.

    I do not want those users to have to be a member of a distribution group (BlockExternalEmail for example)

    What methods can i achieve an ad scoped membership for this transport rule without a distribution group.

    Both mail-enabled security groups and distribution groups create a ... distribution list.

    Thanks

    The reason I want to try to avoid a group is that it seems odd for such a group to be able to be emailed as a distribution list when they have nothing in common other than that external email is blocked.

    I would prefer a group based method that doesnt force that group to be "emailable"


    in that case , hide it from the Address Book and set delivery restrictions on it. No one wil know its there. then you can use a group to your liking. Its really the easiest way to manage this.

  • Hi,

    Based on my knowledge, use a distribution group is the easiest method to achieve your goal.

    Or you have to set a transport rule for every user.

    You could use an attribute on their account or just add each user individually to the rule.

    Why dont you want to use a group?

  • Hi,

    Please create a group for the users and add them to the group. Once done, set up the rules as below. In this example, the group is called "205 (12)".

    Rule 1:

    Rule 2:

    Please test and let me know if this stops the users being able to send and receive external email.

    Let me know if this answers your question.

    Thanks.

  • Yes that should work thanks

    I asked the question because I wanted a method that didnt force the group to be "emailable" as it seems odd and something i would rather not have to force.
