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? I've included the header (modified user/IP addresses) in case it's helpful.
