Frank is pretty adamant about this. I really don't know.
Then test it. Copy your v=spf1 policy to sp2.0/pra and use
a special exp= for the latter. You need a -mechanism like
-all. That should work with Sendmail's Sender-ID test.
For a future OE and OL Sender-ID implementation it's tricky
to log "mail probably deleted" events, maybe try something
like -exists:%{ir}._log.%d instead of -all with a dummy BL
*._log.your.domain.example = 127.0.0.2
I've no idea how OE and OL are supposed to get the sending
IP, major parts of SPF resp. Sender-ID don't work for MUAs.
Unless you can configure something like SpamCop's MAILHOSTs
to identify the relevant Received: header. That could be a
support nightmare for all mail providers.
The darned thing hasn't been tested enough
ACK.
The obvious thing would be for somebody to throw together a
SenderID clone, good enough for logging purposes, and run
it on several servers to get some clue what might happen.
I hope that's what Sendmail does.
Probably AOL is doing exactly that
Their ?all shouldn't cause havoc. Until some cute OE users
(and they are cute, aren't they ? ;-) decide to handle ?all
as spam.
