Hi. I used fetchmail for a few projects over the past 10 years,
and was curious how it deals with SPF (Sender Policy Framework,
http://spf.pobox.com).
If fetchmail retrieves a remote message, then resubmits it locally
on port 25 with the original sender on the envelope, those messages
would be blocked if the local server is enforcing SPF, because the
local machine's ip isn't listed as a valid sender for the domain
which originally sent the mail. :(
I see in the fetchmail 5.0 feature list that:
* Fetchmail can be told to fall back to delivering
via local sendmail if it can't open port 25.
Is there any way to make that the primary behavior
instead of just a "fall-back"?
Then again, if the MTA handled piped mail similarly to mail
received over port 25, by inserting the machine's default ip
address, it still wouldn't work. Not sure if the MTAs do
that or not...
It reject messages only, if you have forgotten to use the "invisible"
option in fetchmail, which prevent it to insert local "Receive:" Header
Anyway, any thoughts on the matter would be greatly appreciated!
Thanks,
