I understand that Courier supports SPF but not SRS. Just in case I missed
it: if I have a webserver (on the same machine) with a mailform...howto?
E.g. user@gmx.... fills out the mailform and the mailform generates a mail to
the company's responsible recipient who has her/his mail account on some
other mail server on this planet. The mailform uses "user@gmx...." as sender
address to give the recipient a chance to reply directly to that email.
Classical problem: the recipient's mailserver gets an email from "gmx.de",
gmx.de supplies SPF info, our host is not one of their mailhosts, mail is
How can one solve this problem? Possibly call srs from within the mailform
script and generate a SRS compliant address instead of using the original
sender adress? But then: what in case of a bounce or reply when Courier does
not support SRS?
