I set up a disussion site on our SBS 2008 Sharepoint server. I set it up to receive emails according to the instructions on this blog:
All is working fine as long as the emails are coming from inside our domain (using outlook or OWA). But when an email tries to come in from outside the domain, it is bounced back with the following message: "Recipient rejected: access denied"
As per the instructions, I have set up the external email address in the site email settings as blah@companyweb. Then I set up a Mail Contact in the EMC as per the instructions using the same EXTERNAL address blah@companyweb. As expected, exchange configured other email addresses according to the recipient address policy and now there are three addresses set up for the mail contact. email@example.com, firstname.lastname@example.org and email@example.com.
When people address an email originating from outside our domain - to firstname.lastname@example.org, this is when the email is bounced back.
Any help is appreciated. This is driving me gray.
