Hi,
I have a postfix-2.10.5 server on fedora, and have several users that
forward their mail through to gmail. This is apparently enough to
break SPF and make gmail think I'm the originator of the email,
instead of the actual sender. Consequently, gmail considers it spam
and moves it to a spam folder.
Is there anything I can do, including somehow rewriting the email, to
get gmail (and others, for that matter) to accept these forwarded
emails without considering them spam?
Can they be rewritten using our SPF information, somehow?

perhaps with fedora read

That sounds like a great solution, but it appears to rewrite every
address, not just those which are to be forwarded:
- Due to the way PostSRSd is integrated with Postfix, sender addresses
will always be rewritten even if the mail is not forwarded at all.
This is because the canonical maps are read by the cleanup daemon,
which processes mails at the very beginning before any routing
decision is made.
Have you used this? Is that the proper way to interpret what it does,
that it affects every "From" address?
Thanks,
