Exchange server's internal name exposed in mail headers

by on Jun.09, 2011, under Computer Stuff, Windows Info

For some reason, Microsoft’s default configuration for Exchange 2007 and 2010 exposes the internal server name in the mail headers, which causes most reverse-record-checking sites to bounce your email.

##EXCHANGE 2007##
To address this issue, you must remove the “NT AUTHORITYAnonymous Logon”? permissions from the send connector. Open the Exchange Management Shell, and do this:
>get-sendconnector (this will show the name of the send connector.)
SEND CONNECTOR NAME

>get-sendconnector <send CONNECTOR NAME>? | Remove-ADPermission -AccessRight ExtendedRight -ExtendedRights ms-Exch-Send-Headers-Routing? -user "NT AUTHORITYAnonymous Logon"

## EXCHANGE 2010##
1. Go to Exchange Management Console
2. Under Organization Configuration, select Hub Transport
3. Select Transport Rules, then “New Transport Rule”
Give the Rule a name, then set the following:

Conditions: Sent to Users Outside the organization
Remove Header: Received
Exceptions: None
