My situation: So I've configured the outgoing email in sharepoint 2010. We use a third party host for our email, mail.example.com, and I want email to send through that. I am guessing the hangup for notifications is either firewall or athentication related. I am completely lost.
My Environment: We are very small and have just 1 server running SBS 2011 and Sharepoint 2010. We access sharepoint using this url in a browser
