Subject:[courier-users] SPF and mailing-listsActions...

Apologies if this is a generic SPF question not related to Courier specifics. If so then please point me in the right direction.

Say a mailing-list has 70 members and the original owner of the list sends as...

From: use@domain.org To: some@domain.org

and one member is on our mailserver with fairly strict SPF checking. The first email from the above user gets through to our list member because it's From: @domain.org matches the @domain.org SPF authorized mailserver. But when other members of the list reply to this list they get a bounce from our mailserver saying their email From: address does not pass our mailservers SPF checking.

Because one of the list memebers is on our mailserver, which has strict SPF checking and presumably the others do not, it seems to be causing quite some grief for other list members (not counting our local user is not getting the other list member replies) and is threatened with being banned from this list.

Is there a workaround for this situation ?
