    Recipient Policy controls what addresses Exchange thinks it is responsible for - so check that the policy for that domain is still enabled.

    Drop in to a command prompt and type


    and press enter. That resets the IIS system which manages the SMTP server.

    Your server isn't announcing itself properly. Not that will be the cause of the problem, but it could cause you to have email delivery issues.

    What happens if some internal user sends an email to the address mentioned?

    Is the recipient policy that controls that domain the default recipient policy or an additional one?

    We have no problem sending anywhere and receiving emails now from some domains. Nothing has changed still. From Yahoo it still says the same thing and some others are getting. on 4/26/2006 11:31 AM
      You do not have permission to send to this recipient. For assistance, contact your system administrator.

    Is there a way to flush DNS cache?  It is making no sense. Yes there is only one domain and that is the default. It has been working for years and all of a sudden with no apparent reason does not work.

    Accepted Solution

    You cannot control the DNS that Yahoo are using. If you are starting to receive email on that domain then they could be using old information, you will have to wait for that to be flushed out - it will take three days (48 hours+).
