My client is using a third-party service (Constant Contact) to send opt-in bulk email. I need to publish an SPF version 2 record.
Openspf.org has a nice wizard to generate a version 1 record, but I can not find any information anywhere on version 2.
Can someone provide me a few documentation links on SPF version 2 records? Any online wizards to generate an SPF v2 record?
