I have a situation where I have to provide email connectivity over a low bandwidth (64k), unreliable satellite connection to approximately 400 users. I have configured two SMTP connectors between my main site and an exchange server at the remote site. One connector is for general transport and has a message size limit of 50k, the other connector is meant to be used for 5 users who have to have the ability to accept large messages up to 1MB in size. I'm having problems with blocking or allowing transport over the connectors by recipient address. The incoming emails can be from anyone internal or external (internet) and have to be filtered based on size and recipient. If they are under 50k, they get sent over the first connector (lowest cost route) and if they are to one of the 5 special users, they can be sent over the 2nd connector. Exchange 2003 only allows one recipient filter, so I can't use it as the sort method. Is there any other way to block by recipient address? Any suggestions or ideas? I have to use SMTP connectors as Routing Group Connectors have even less filtering/routing options. Thanks, Scott
I presume Exchange 2000/2003 as you mention Routing Group Connectors. Thus, enable Delivery restrictions on the SMTP connectors and assign Security Groups for who can use them. Remember to set this key: http://support.microsoft.com/kb/277872 Oliver
That allows filtering of internal users sending internally or externally to/from that site, but is not capable of restricting external (internet originating) emails and routing those over the proper connector based on recipient. Unless I'm missing something? And yes, this is Exchange 2003 as mentioned in the original post.

Ahh I fully understand what you mean now. You won't be able to filter external recipient (Internet) addresses Oliver
Thanks for your help. Do you know of any other way or third party tool that would allow me to route traffic to a specific SMTP connector (or SMTP Virtual Server) based on the recipient address? My only thought right now is to manually create a huge recipient filter containing all internal addresses at the remote site except for the VIP users and apply it to the large message SMTP Connector. It would prevent delivery of large messages to any of the non-VIP users over that connector, but seems very backwards, as well as being a huge administrative nightmare and bad solution, even if it would work. I guess what I'm trying to find is a Permit filter for specific recipients, rather than the Deny that the built-in recipient filter has.
