Ok, I have an Exchange 2007 server.
 I am using an external antivirus/spam solution "Postini",
 I am configured to send outbound mail through postini as well.  This is configured as a smart host.
I need to setup the exchange server to
Allow Anonymous Access from the internal network.  For other servers, scanners, alerts to relay anonymousely.
I need to allow postini to relay anonymousely through this connector.  I need to specify their subnet.
I want to allow internet users to authenticate for smtp and pop3. - Pop3 portion is working properly.
All anonymous internet users cannot relay.

Can this be done with one receive connector or what?

yes just create a receive connector, and allow on it anonmous permission and that is fine, i the properties of the receive conector, define internal server and the poistini server as allowed to relay.

Ok I get the part where you specify the relay hosts, and

Here is how I set them up
1.External
Network
Local Ip's to receive mail - all available / port 25
Receive mail from remote servers that have these ip's - 0.0.0.0-255.255.255.255
Authentication - following are checked
Basic
Permission Groups Following are checked
Exchange Users

2.Other
Network
Local Ip's to receive mail - all available / port 25
Receive mail from remote servers that have these ip's - 192.168.1.0/24 and 64.18.0.0/20
Authentication - following are checked
None
Permission Groups Following are checked
Anonymous User

This look right, it seems to work fine.  
Thanks for the help Busbar

Ok My configurations of the receive connectors is correct.  Here is what's missing
Powershell -
Get-ReceiveConnector "Anonymous Relay" | Add-ADPermission -User "NT AUTHORITY\ANONYMOUS LOGON" -ExtendedRights "Ms-Exch-SMTP-Accept-Any-Recipient"

Get-ReceiveConnector "Anonymous Relay - "  this is the name of the connector.  Lost emphasis on the  cut and paste.
