Multi domain internal routing Accepted Domains

Hi,

(example domain names, acme.com and beta.com)

I have an Exchange 2007 single server that has two domain names associated with it. We own both and MX DNS etc all working.

DNS internal is acme.com, with no reference to beta.com

100 mailboxes - acme.com    authorised domain  - mail works fine in and out - to person, disty group,

10 users (going into their acme.com mailbox) -  beta.com authorised domain.

The 10 users are have @acme.com email address (reply) and beta.com email addresses.

So as an example:

Mike - mike@acme.com, Mike@beta.com
Finn Finn@acme.com, Finn@beta.com


When I email a Mike or Finn directly @beta.com they receive the email. Same as their acme.com addresses. (works as expected)

I created a distribution group,  configure it with the email alias of support@beta.com and add Mike and Finn to the group to now get a 550.5.7.1 relay error.


Im not sure what I need to do. I have tried to google this but its quite hard to explain via the search engine. I have also tried an email specialist site msexchange.org, to no avail.

Hope it makes sense.

Any advice would be helpful.

thanks


Mike

Domains in Exchange are just aliases, so as long as the domain is
a. listed in Accepted Domains
b. listed on the user accounts

It shouldn't matter what combination of email addresses are used.

Does this group that you have created work internally? It should do.
If you want this group to accept email from the internet, have you removed the option that all senders must be authenticated?

Thanks for the reply Simon.

Your right, internally it works fine. Just when its comes from external it seems to be in the delivery queue but never gets delivered (seems confused at where to route.)

 Could you confirm where that is done please?

Accepted Domains is in EMC under Org Config Hub Transport or get-accepteddomain.
The Senders Authenticated bit is under Mail Flow Settings on the properties of the group. It is on the Message Delivery Settings option.

Looked where you suggested but the it doesnt seem to be there. The only place I see the "auth" option is under receive connectors (Server Conf - Hub Transport).

This has nothing to do with Hub Transport. On the properties of the group under recipients is where you will find it. It is a PER group setting.

Simon big thanks,

Works as you said. Its important to uncheck "authenticated users" within the distribution group settings.

As I deleted the groups due to them not working, this was the issue.

Make sure once the Dist group is created you modify that object.

Appreciate you persistence .
