We have multiple clients in our multi tenant hosted Exchange.  Is there an easy way to setup different smart hosts for each client?  Right now it is either outbound through the MX record or a smart host.  We can setup a send connector to route to a specific domain, but I would like to define the internal domain to use a specific smarthost.

Example

we hold these domains

ABC.com

XYZ.com

DEF.com

I want this to happen

ABC.com - smarthost - trendmicro.com

XYZ.com - smarthost - barracuda.com

DEF.com - smarthost - spamassassin.com

Thanks

Hi Todd,

afaik what you're looking for is called sender based routing.

To d that, you need to use 3rd party tools. There is no SBR implemented in Exchange 2013.

Hi,

Actually, Exchange Server can't select a send connector based on the sender address and a direct solution is not available. You may go for a third party tool like 'MultiSendcon'

There is no built-in source based send connectors in on-prem Exchange 2010 or 2013.

You can use:

•  An agent:

We have our own servers in house.  I would not expect I can use them?

Thanks

If you smarthost and sync through Office 365 you can use conditional routing :
