Maybe other people have noticed and discussed this and I'm just behind
the times, but for more than a decade, Google specifically said:
"Avoid changing the envelope sender when forwarding email to Gmail."
lets use forged original sender, works much better :)
(You can see this as recently as last November at
<https://web.archive.org/web/20221127015217/https://support.google.com/mail/answer/175365>.)
default in all mta, at least postfix is to use new envelope sender so
spf works from new sender domain, why not keep it simple ?
note there google will see this non aligned in dmarc since its a forward
Because of that, we didn't do it. But I noticed that the current page
at <https://support.google.com/mail/answer/175365> now says the exact
opposite:
"Change the envelope sender to reference your forwarding domain."
So I guess it's time to add SRS rewriting for Gmail addresses...!
no
SRS just hide all fails, it does not solve all fails, don't use SRS
google is right, use local adresses on the forward host that can bounce
back to original sender local, if this is complicated, don't use
forwards
Life is good, use linux
