Exchnage 2007 receive connector permissions settings

Hello,

This is what I am trying to do:

1. First User is in AD and Exchange (Name and Display Name: User, Email Address user@abc.com)

2. When first user sends an email using his account the sender shows up as "User", which normal and the way it should be.

3. There is a second user who occasionally has to send email as the first User, but in these cases the email sender must show "User2" eventhough the email address stays the same user@abc.com !


The way we are trying to achieve this to have User #2 send using POP/SMTP using User #1's account and set "User2" as the sender name in Outlook.

This works fine as far as the external recepients go (they see User2 as the sender and user@abc.com as the email address).

The problem is the for internal users Exchange automatically resolves the sender name to the user name found in GAL which is "User"

I know that for Anon senders Exchange 2007 will not try to resolve email addresses to the GAL sender for security reasons.

What security setting would I have to set on the Client receive connector so when an exchange user (non anon!) send an email using SMTP then the sender's name would NOT be resolved internally...

I am not sure I understand what you are saying?
If you authenticate with Exchange and send an email then it will resolve your name if it is available.

Exchange will always resolve the addresses to internal display names, there is no way around this.

demazter,

If I set the receive connector to Anonymous and User2 sends thru that Exchange does NOT resolve to the internal display name. Except this way I just  created amd open relay.
