Hi, Folks:

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. 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?

Thank you,

SPF v2 is really Microsoft's SenderID...
Information on this are here: and Microsoft's site:
Info on syntax here:
WRT building it - just copy you spf=v1.0 record and replace the "ispf=v1.0" part with "spf=v2.0/mfrom" all rest remains same (don't use /mfrom,pra as PRA is not working with all  MDAs...)
Have fun!
