Notify users that recipients of their email cannot reply to us as sender blocked

[ScottLoveland8675309]

Internal senders would like to know when they are sending to an address that is blocked from sending in email to us.

For example:

Howdy@Doody.com is blocked (either rejected through Senders Verification Exception Table) or is listed in a Sender Group that sends the message to reject mail flow policy.

When someone sends a message to Howdy@Doody.com, they would like to know that Howdy@Doody.com can't respond (and potentially, the message is not sent).

Thoughts about how I can orchestrate this without maintaining two lists?

Any reject policy would basically block the connection before there is any chance of notifying or processing.

Also, the ESA cannot correlate data for what happened with an incoming email to notify senders later on for outgoing emails. That would require some form of list to be maintained dynamically whenever we block something which currently is not an option.

As an administrator, you can certainly allow certain connections which would otherwise have matched a reject policy and generate notifications using message filters or manually maintain a dictionary for which notifications are to be generated.
