- Requires two SPF records (SPF1 and SPF2.0/PRA)
Can be fixed with either op=pra on SPF1 or scopes on SPF2.0. This
is not so much a drawback of PRA as a reaction to Microsoft grabbing
all the SPF1 records without some kind of opt-in (e.g. op=pra).
- Less effective when not used with SPF1
Less effective for MTAs and mail admins. More effective for end-users.
Benefits:
- Microsoft Support for SPF
- Can be effective when used with SPF1
- Can help phishing by displaying the PRA at the MUA
