Issue with message delivery restrictions

Asked By 0 points N/A Posted on -

I have a problem with Message delivery restrictions. I have Exchange 2010 SP1 with Rollup Update 5. I have checked “require that all senders are authorized” in one distribution group, but everybody from outside of our organization are  still able send to this group. Why?

Hi there,

I recommend you check on the receive connector on the Authentication tab if externally secured option is ticked.

If the problem still persist them you should then create a new Universal distribution group and check require that all senders are authenticated and send mail from an external provider (gmail,yahoo or Hotmail) and can still receive the mail


msExchRequireAuthToSendTo = True.

Be sure to check the Internet Receive connector after everything has been done.

This is normally known as message throttling.

I hope the given solution helps you solve your problem, since the Microsoft Exchange 2010 is needs various updates to properly function.
