Quickbooks support might as well work at Walmart.

This should work:

goto smtp2go.com and create a free account. Once in there create an SMTP account (that is for sending mail). Make sure to copy your SMTP username and password (NOT the account you use to create the main SMTP2GO account, the one you create once you get INSIDE the SMTP2GO website... the SMTP user). Copy all the server settings and then put those in quickbooks and it will work.
