Exchange distribution groups available outside

Hello all,

I have a SBS2008 box with Exchange 2007. I have created distribution groups and they seem to work fine internally. but how do i get them to work from outside? In other words I have a Dist group called Information and the email address i made for it is info@mydomain.com. There are 4 users in this distrgroup. So internally works fine when I send an email all 4 get it. I am now trying to send from any email address outside and does not seem to go through but all email to regular email addresses work fine. Any ideas? The primary smtp address for that dist group is set to info@mydomain.com.
Also, is there a way to make a Security group a dist group as well. I have a sec group named "Allusers"  and if i want to make a dist group for it i have to create a second group called Allusers2 because it will not let me use the same name for dist group. Of course i can only use the sec group for assigning permissiosn to folder and files. Anyway to use just one group name? Thanks,

Jimmy K

By default Exchagne 2007 groups are only able to be sent to by users that are authenticated.  You need to open the Exchange Management Console and...

Recipient Config ->
Distribution Group ->

right click your group and go to properties.
Under the "Mail Flow Settings tab there is an option "Message Delivery Restrictions"
Under that you need to UNCHECK "require that all senders are authenticated"

Then you should be good to go.
