hm. I feel that if you force us to use a mechanism that is broken by
design (SPF), you should support the extra mechanisms it requires (SRS)
or not allow your customers to set up forwarding at all.
"-all" is not defined as "don't forward my mail". Switching to "~all" or
any other setting would just water down SPF authentication. Why use it
then in the first place?
But I guess we had those discussions here before.
Indeed. Some people believe that -all is useful for general mail, and somehow
the rest of the world should know that they don't really mean it and expend
their own effort to work around it. They are wrong, but we'll never persuade them of that.
Appendix D of RFC 7208 is clear enough. Alternatively, one can make it
explicit by terminating its record with, say, ~exists:%{ir}.list.dnswl.org -all
