Mailing list traffic will still be accepted, as long as the mailing list's domain has an SPF record that validates the mailing list's return address.And what’s happening if the mailing list’s domain doesn’t have an SPF record?
What happens then is that the mailing list admin needs to be educated. lists.sourceforge.net. 7200 IN TXT "v=spf1 redirect=_spf.sourceforge.com" This is not rocket science.
In this case it shouldn’t be treated negatively and mail should be accepted.
Sure, if that's what you want to do, just turn off SPF completely.
But your above statement sounds as if mail could be rejected in this case. I wonder how many mailing list e-mails I’ve already lost. :-(
If you read the courier man page, it explains, in detail, what each setting does. The ultimate decision is the recipient domain's. If the domain wishes to use SPF to check MAIL FROM, it can. If the domain wishes to use SPF to check the From: header, it can do that to. One is not a requirement for the other.
