Hi guys,

I just wondered, if it's possible to detect the message of other servers
while on transport AND afterwards discard the outgoing message as spam?

Example:

2014-06-03 21:45:33 1WrueK-000271-Du <= [email protected]
H=(83.246.80.141) [190.107.140.77] P=smtp S=709
[email protected]
2014-06-03 21:45:35 1WrueK-000271-Du ** [email protected]
<[email protected]> R=remoteusers T=remote_smtp: SMTP
error from remote mail server after end of data: host mx03.t-online.de

If the problem isn't obviose, thats whats happening:

The user has a forwarding mailaddress on my server. The destination is
i.e. t-online.de, german telecom.
The spammer sends his mail to the forwarding mailaddress, my server does
what he should do,
and t-online rejects the mail. in 99% of time, that is a correct reject.

( Yes, we offer antispam tools, but those users don't activate them. )

Now the mail creates a delivery message, which can not be routed and
stacks up in the queue. Sometime a valid emailserver just rejects it as
spam too, same problem, different reason.

Here is the idea, if it's possible to mark the outgoing message as spam,
when the targets says it's spam, then the delivery message could be
skipped and the spam be discarded. Problem solved.

How can we archive this ?Is it meant to be possible by exim ?

best regards,
Marius
