forwarded mail - header removed?

Greetings to all maia-users,

I haven't posted in here for quite a while now, one of the
reasons is
that Maia runs fine and without problems ;)

Now that the holidays give me some time to catch breath I
look through
the various smaller itches to scratch and one of these is
the following:

As I am member of a developer-team I have an email-address
there. The
postmaster of that domain forwards the mail to one of my own
addresses
here (managed by Maia). He does some spam-filtering on his
servers
already and flags the potential spam with a X-header called

X-Spam-Flag: YES

At least he says so ;)

Unfortunately when I get these mails into my Thunderbird
that header is
gone ...

Maia tags nearly all that mail as Ham as it comes from the
spamfilter-system there (I assume). It just doesn't get
enough points ...

So the questions:

How should I handle this correctly?
Where is that Flag removed? SA?
How do I configure my boxes to make use of it?
Write a specific SA-rule?

I would already be happy to just have that flag and filter
mails into a
folder on my client (or via a sieve-rule, maybe).

I would like to hear your suggestions on this.

Thanks a lot, have some nice days, best wishes for 2008,

Stefan

The trusted relays parameter might help:

Thanks, David, I will follow that pointer, although I do not
yet fully
understand how to use that .... trust the relay or not ... 


Thanks anyway, best regards, Stefan

It means you trust the relay not to be a source of spam. It
might relay
spam through a mailing list, but it is not itself a source
of spam. What
that means is,  SpamAssassin will ignore Received: headers
generated by
a trusted relay, and instead treat the message as though it
originated
from the next Received header. This prevents SpamAssassin
from scoring
the message too low because it passed through the trusted
relay, and
makes it raise the score if your trusted relay got the
message from a
known spam source.

Aaah, thanks for that explanation, Greg!

Now I understand this much better than when I read that
website late
last night ;)

I added a "trusted_networks" line to my SA-configs
now, we'll see.

Do I have to add "127.0.0.1" and the local IP of
the server as well or
is this unnecessary?

Thanks again, Stefan

Following up myself:
For SA 3.1.8 (which I still run here) this seems to be
necessary.

It helps so far, thanks!
