How to set up the MX record and SMTP Configuration
I have two questions regarding my Exchnage 2010 configuration
Brief description
I have one Mail Server (that house my mail store)
I have one Client Access Server that is also my Hub Transport Server
I use Barracuda 400 application as my Edge Transport Server
1st question: Do I set my MX record for DNS to point to my Barracuda System or should it point to the Mail serve or Hub Tranport Server.
2nd question: I have applications running on now Exchange Severs that need to send email out external. I tried configuring a send connector for those network ip but it does not seem to work. Should I have them configure to send out email via BarracudaSystem?

This is the weirdest thing I have tried what you but have suggested and the applications still cannot relay through my sever. My configuration
Hub Tranport
Receive Connectors - Custom
Allow2Relay
General - FQDN is correct
Network - Receive mail from remote sever - 172.16.0.0/24 and 172.16.19.191
Authentication - Transport Layer Security (check); I had even check Basis Authentication
Permission Groups - none check and had tried it with Anonymous users checked
They still cannot send email, what am I missing

Also, I can get it to relay if explictly add an i.p. address but it does not work if try to use the network with CIDR mask. For example 172.16.0.0/22

It solved all but one problem where I still have to put in individual ip address of devices needing to relay an email message.
I would set up a new 'Receive Connector' on Hub transport server with a list of IPs of the application servers that need to send to it. The existing send connectors will look after sending out email to external users.
