Re: @debian.org email forwarding and SPF

I understand it.

I think you may be misunderstanding a few points. One is that there is no such thing as a mail server doing SPF checking on a certain domain-- it is all domains publishing SPF or nothing. More importantly, if the original sender's domain publishes SPF, and the developer's ISP does SPF filtering, and Debian's forwarding does not employ SRS, then the forwarded email you describe will *not* make it through, even if debian.org is publishing SPF records. The reason is that when the message hits the ISP, the envelope from won't match the machine relaying the mail (*.debian.org).
