I use a simple emailing program written in .Net C# - .Net 3.5
the class I use is System.Net.Mail
the program worked fine on one server and since moving to a new 2008 R2 server does not send emails out.
I am yet to debut it - and drill and get to any errors. But before that is there any known issues or tweaks to setup in Windows Server 2008 R2 to get emailing work ?
Thanks very much in advance.
