Where can I find out more about how / why SRS does not help.
I've been aware of SRS for quite some time and I always thought that
it did address SPF issues caused by forwarding messages.
SRS "didn't work" (catch on) because there is/was a fundamental
concept/idea/methodology/philosophy/taboo that the Return Path
(5321.MailFrom) should never be changed/altered/tampered with along
the transport path/route.
It's the same long time mail engineering ethics mindset against
altering the 5322.From original/authoring address to deal with 3rd
party issues and ADSP/DMARC strong policies.
