Emails from Constant Contact will not work with distribution/forwarding lists

I have a client who uses Constant Contact to blast out mass emails.  Whenever someone subscribes or unsubscribes from this blasting list, a summary report is sent to an address, which is specified/validated in Constant Contact.

I have two situations in which this is failing.  For the first, the emails seem to reach the original delivery point just fine.  In this particular case, this is simply an account on an in-house Exchange server that can be accessed in whatever means desired.  This account is set to forward a copy of each message received to the client, who is on an external email address.  When I send a message directly to this account, it forwards on without a hitch.  When messages come through from reports@constantcontact.com, they do not get forwarded.  Using the Mail Tracking Tool, it tells me the message is successfully delivered locally, then Outbound Transfer of Message starts, then an NDR is generated.  The messages never even hit the Reflexion server.  Constant Contact does not have an inbox which catches these NDR messages, so I cannot even see what error is being generated (can't find it in the event logs, either).

The other scenario where this is happening is with a hosted Exchange distribution list.  When reports@constantcontact.com messages are set to go to the address of the distribution list, nobody gets the message.  Sending an email from my account to the distribution list works fine.  It must be set to go directly to a user's mailbox to get anything from reports@constantcontact.com.

In both cases, appropriate email/domain addresses have been added to white lists.

Has anyone else run into this problem with Constant Contact?  How did you fix it?

Not entirely sure what happened, but the address with just the distribution list (which was on a Hosted Exchange site) started working of its own accord.

As for those being sent to the in-house Exchange mailbox and forwarded to an outside address: Discovered the Global Setting in the Exchange 2003 System Manager for email coming in from the internet was not set to allow automatic forwards, replies, or OOO messages.

-Exchange System Manager > Global Settings > Internet Message Formats
-Right click "Default" > Properties
-Advanced tab

All forwarding appears to be functioning normally now.
