I have a virtual user on one of my domains who's getting her emails that I
forward bounced because her email host checks SPF headers, and my qmail does
nothing with the email header before forwarding to her. It's a SwSoft Plesk
qmail with several patches, including SPF checking, but it does not do
anything during forwarding other than add the spf-checked header. On teh
SPF site, there's the following bit of info relating to forwarding. Can
qpsmtpd handle either this or SRS?
from http://www.openspf.org/Best_Practices/Forwarding:
For non-sender-rewriting forwarders, accept all mail without checking SPF
(any SPF results are meaningless). Hopefully, you (or your user) have chosen
a forwarder that checks SPF before forwarding. If your implementation allows
it, also check SPF for a "pretend" MAIL FROM that your forwarder could use
(the original recipient RCPT at the forwarder before the email was
forwarded). This verifies that the forwarded mail really came from your
trusted forwarder.
