The user has said it's spam, after all.
The user trusts his good outgoing mail to that MTA - why should she not
trust her spam to the same MTA?
It's a different case. We're sending email to an address at that MTA,
and drawing attention to it.
The main problem here, though, is that the user thinks they're reporting
spam, but in fact they're generating it.
No, no. I was assuming that the user was sending reports to a reasonable
address, not one made up from the name it uses to find its POP or IMAP
server.
And not one found in a header in a spam message, either, I hope.
(See other threads for why that's hopeless.) The question is
whether it's a problem that the spam report takes a detour through someone
else's mail system on its way.
There are two possibilities here:
The user retrieves a message from our mailstore, and attempts to use a
third party address to report it. We'll not likely take much notice of
reports from addresses outside our domain, that are purporting to have
knowledge of what's on our mailstore. If the message isn't still on our
mailstore, there won't be an easy way to verify that it ever was - and
there certainly won't be an easy way to verify that the message in the
report is unmodified.
The user retrieves a message from our mailstore, and attempts to use an
address in our domain to report it to us, but submitted through a third
party MSA. We'll simply reject the message on the basis that we don't
permit such traffic onto our MX servers. We won't even look at the message
body.
Either way, the report won't be actioned.
