Good morning! When a local address - having no local delivery - is forwarded to another mail server which strictly checks SPF, it could be that the sender's domain has "-all" in SPF thus it is not possible to forward that message. BTW it causes backscatter.
On forwarding Courier MTA sets MAIL FROM: to the same address as in the original message's From: header (or the original MAIL FROM:, I do not know) and this - the forwarding - mail server is not on the allowed hosts' list in SPF. Could we have a new option for setting a fixed MAIL FROM: on forwarding to make forwarding possible in these cases? Thank you!!
