is rumored to have said:
direct to mx will have spf pass without +all, on next hub envelope
sender changes, so new spf problem when next hub forwards mails,
You keep repeating this (and equivalent statements) as if it is true.
***IT IS FALSE***
Unless a MTA implements something like SRS specifically to accommodate
SPF, the envelope sender a mail arrives with is the same one it is
relayed with, if it is being forwarded by the traditional "aliases"
and ".forward" mechanisms of Sendmail and Postfix. This practice,
*without SRS*, is still the most widespread form of forwarding
individual addresses to other individual addresses.
i keep what postfix does, not what any other forwarding service does,
its false aswell to not know how postfix works, period
https://mx.junc.eu/dmarc/junc.eu/all.txt prove my incorrect now ?
if you are right i would see more spf pass
