Woohoo. Breaking something and then requiring others to fix it for you and
labeling something that is less reliable as "reliable".
Let's see, I think that's summing it up perfectly:
http://www.idrewthis.org/d/20060619.html
All mailing list forward mail with the original
sender in the
enveloppe
Not true: Mails from the swinog-mailinglist reach my mailserver with
swinog-bounces(a)lists.swinog.ch as sender envelope address
and if you
forward your mail on one server to another one
with e.g. a simple .forward rule it will also re-use the same
envelope from address. Forwarding mail is very common and it is
important to use the same envelope form address in the forwarding
path. Everybody who denies this fact does not understand the email
system and the way bounces work.
If you chose to forward mail this way, then you'd better make sure that
the destination mail server doesn't apply spf checks for mails coming
from the relaying server. or that the forwarding server rewrites the
sender address.
If you're a provider that allows its users to forward their mail to
remote addresses, then I'd advise you to use sender rewriting and thus
offer your customers a reliable mail relaying. That's a marketing
argument.
But in the end, everyone can do whatever they want to do ;-)
No they can't because of self-appointed Anti-SPAM marshals breaking
deliberatly official standards causing marjor pain to others.
