I have the following
Windows Server 20008 R2 with AD Domain, IIS and SMTP Server enabled
SharePoint Foundation 2010 SP1
All I need to do, is to be able to send alerts and workflow emails to email addresses outside of the domain, no incoming email capabilities are required. As I understand it, I do not need Exchange and the SMTP service will take care of outgoing mail.
Since I do not have Exchange installed, in AD there are no tabs for email addresses for the users and therefore no email addresses are associated with the user. So if an AD authenticated user on Sharepoint wants to create an alert for themselves, there is no associated email address for the AD account that Sharepoint authenticated him with. So how could Sharepoint know what address to send the alert to?
I have noticed that if i click on my user name at the top right of the Sharepoint site and go into my settings, the email address field is blank. If I enter an external email address here, will Sharepoint use that address to send the alert out to?
