Send email from Outlook Express through Exchange server from outside of domain
Posted on 2007-11-28
I have an Exchange Server running on a MS SBS 2003. I have a user that will need to use Outlook Express to send and receive mail from outside the domain. I have it configured and working for this user to receive, but I cannot send email through Exchange. I know it's has to be something I am missing on configuring a user to send email through Exchange when not in the building. At the same time, I do not want to create an open-relay. Any help on this would be greatly appreciated. Thanks.
