I use mxlogic as my email washing service and as a SmartHost. From time to time, we get a fail on SPF lookups and a sent email gets rejected back to us. Our current record is
"v=spf1 +a +mx ~all", where if I interpret this correctly, means
-the sending server must have RPTR
-Be in the MX record
-soft fail otherwise.
and I want to change that to
"v=spf1 include:mxlogic.net ~all" meaning:
-include mxlogic.net as valid sender of email for said domain.
Is this right?
found this article to be fairly clear, but I was hoping to get some realworld opinions on it before I hit "go".
just in case it matters, Exchange 2010 is our server
