Hi,
I have a forwarder set. All the outgoing mails relay via a3rd party mail
app . In the 3rd party app I have mentioned the list of allowed domains
that can send out mails.
But as all the forwarder mails have from address as the actual from, 3rd
party app is rejecting it. So I was thinking of changing the envelop header
of the mail to that of actual recipient in the server. Is it possible to
achieve it via routers? Is there any other way I can handle this?
I aren't using the standard jargon (there is no good reason
why you should) and I'm finding your description a little
difficult to understand, but I think you have the right idea.
I *think* the 3rd paty app is rejecting these emails because
they fail SPF; the usual way to fix this is indeed to use the
incoming recipient address (although it is not commonly described
that way) - or something based on that - as the outgoing envelope
From address. This is known as SRS and I think that would be correct
thing for you to do.
I'm afraid that I don't remember how to implement SRS in exim.
Good luck,
