The case I am talking about is for a person that gets email from a postgres
mailing list at server A and forwards it to server B. If server B checks
SPF records it will reject this message because it is not coming from a
server authorized to use postgresql.org as an envelope sender domain.
This is something that probably won't affect many people, but it would
still be nice to give people a heads up before turning it on. That way
they can adjust things so the mail gets through. (By such methods as
using SRS on server A or changing their subscription address to server B.)
