Windows 2008 SBS with 2007 and Sharepoint 3.0. I can create the email contact and it works fine but when I attempt to send the email with the attached document I get the following error and the email never makes it to the document library. #554 5.4.4 SMTPSEND.DNS.MxLoopback; DNS records for this domain are configured in a loop ## Can I get the STEP by STEP procedures to mail enable a Document Library on Sharepoint 3.0 with EXCHANGE 2007 on the same server or is there a simple fix that I can do to get this resolved. PLEASE advise ASAP. I have been working on this issue off and one for weeks and the client really wants this for their timesheets. Thanks in advance! Mike Pratt
