This is all good, but I also need to know the following:
- a log of each request that was failed, including the date,
sender address, the purported 'mail from' header, and the
intended recipient.
Isn't this info logged already by the standard implementation? Can't you just
grep it out of the postfix log? (i'm no postfix expert)
- how to make postfix send an explanation back to the sender
of why the email was rejected.
When mail is rejected, any conforming spf implementation will read out the spf
records exp domain, and use that as the 550 error message. Usually, this
message is then send back to the sender by the original mta.
- ideally, I'd like to send a rejection reply to the sender
and quarantine the email instead of rejecting it, so that
I have a full copy of the email to examine in case of problems.
This is NOT ideal. Don't do this. If spf rejects, this most likely means the
sender address is forged. You don't want to harras innocent bystanders with
automated replies, now don't you??
