External emails not going through to internal distribution group

Experts,

I have created a distribution group in win SBS 2k3 server (Exchange 2k3) which works fine for internal users but for external users they get the following error:

From google:

"Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 Rule imposed mailbox access for logistics@xxxxx.com.au refused: user invalid (state 17)."

I have set the setting to receive emails externally however i still get error messages.

Any help would be great.

you need to allow external users to send mail from outside users and need to set the following settings:-
Select a group -> Properties -> Mail Flow Settings -> Message Delivery Restrictions -> Properties -> Untick “Require that all senders are authenticated”
also have a look at http://social.technet.microsoft.com/Forums/en-US/exchangesvrgeneral/thread/56e342e4-1aed-4164-a7b9-0e5fabf102f0/

Do the following:

1. Click Start, point to Programs,
2. Click Administrative Tools, and then click Active Directory Users and Computers.
3. Now browse to the distribution group and Right-click then select Properties.
4. Click the Exchange General tab.
5. Under Message restrictions, uncheck From authenticated users only check box.

Hope this helps!!

Hi Guys,

Thanks for the responses.

Under Message restrictions, "from everyone" is already ticked( was ticked from the start).

Ajay Sharma

Please see image below:

The following tickbox that is highlighted needs to be deselected:

I don't think that exchange distribution group are recognized as <to> for smtp protocol, which is used by external mail servers, to do that you need to make a mailbox and then set it up to forward his incoming emails to that group

Group Resolver is an privileged process on the server, external email servers like gmail access your server as anonymous.

good luck

Hi Akicute555,

Under properties i dont see "mail flow setting" on exchange 2k3. I access this group via server managerment-> distribution group and also via Active directory.
