Exchange 2010 Edge service

[DevilsAdvocate]

Hi all,

 

We have two edge servers setup that i inherited when i took over. Haven't done much with them as they work perfectly fine and everything. However lately we've been getting a fair few emails addressed to recipients that don't exists sitting in the queues. To counteract this i thought i'd setup the recipient filtering to 'block messages sent to recipients that do not exists in the directory'. However, this appears to then block all incoming external mail. Does anyone have any experience with settings this up and with what I need to do to get it working correctly?

 

Thanks in advance.
