We're looking to set up an e-mail sub-domain for a project, and we need to set up a catch-all e-mail address, so whether people send project updates to project1234, or project4321, it will redirect to the one existing e-mail account.
- I've set up the sub-domain MX in our public DNS.
- I've set up the sub-domain in EMC, per this article. We do not have an edge transport server, but the same settings are under Hub Transport, which I thought would be the same.
- I've set up the catch all e-mail address per this article.
The sub-domain works when I send directly to the one existing account with an e-mail address in the sub-domain, and it works if I set up specific aliases on the account, but it's not working as a catch all. When I test from my Gmail to a non-existent address on the sub-domain, it is rejected as an unrecognized recipient.
At first I considered that it might be our spam filter (McAfee hosted) blocking these messages. But when I added an alias in Exchange and did not set up the user in McAfee, it still came through, so it really appears to be something misconfigured or missing in Exchange.
I set up the Transport rule to be "when a recipient's address matches '@sub.example.com$' copy the message to 'existingAccount@sub.example.com'"
I've also tried "when a recipient's address contains specific words 'sub.example.com'" and any other variation I could think of to get a generic catch all for the sub-domain... nothing has worked so far, except creating an alias (which would defeat the purpose of having a catch all).
Does anyone have experience with setting one of these up, and so could provide direction on what I'm missing?
P.S. the NDR
