Emails from Constant Contact will not work with distribution/forwarding lists
Posted on 2011-09-26
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 email@example.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 firstname.lastname@example.org 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 email@example.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?
