In our Exchange 2007 server, there are about 15 mailboxes and one user would like to have some sort of email restriction.
How can I configure Exchange to allow or block a particular list of external users and internal users to directly deliver their emails to his mailbox. For example, he does not want to receive emails from a few internal users and want to receive emails from allowed external emails.
Currently, the old sysadmin guy made a mail-enabled security group (universal) called "email addresses allowed send" and added internal users to this group as well as external users (gmail or yahoo users). In the security tab of the group, there are many groups which make me confusing - the groups are:
Exchange servers recipient administrator
Windows authorization access group
Enterprise domain controller
I am having difficulties to find which group has the send to permission.
For a testing purpose, I have used a different user account to send an email to his inbox but it does not deliver to his inbox - I can see it was sent from the user's outlook. This email should deliver to his mailbox as the user account is added to the security group but the sent email is not delivered to his mailbox..
