Turned out that Anna from Support was able to sort things out and get things working with the SPF issue. Thanks Anna!!I don't think so. That's an SPF error which basically indicates that the sender is using a relay when the server otherwise doesn't allow it. Step 4 here (https://powerproductsandservices.com/public/mailserver/Mailserver Security.pdf) explains it pretty well.
One more question if applicable...You need to use ftp I assume and edit the file. I checked mine and it was already set up that way.
