SA: adding a custom header when spam is detected

[CMuelders]

Hi,

is it possible to configure SA in a way, that a custom header line is added, when it detects a mail as spam? Specifically: I want it to add "Precedence: junk", not a custom line like "X-Spam..:".

Any help?

It's not a header, but the GUI has an option to add a prefix to the subject line. Go to Global Settings, click on the AS/AV tab, and you'll find the field where the subject prefix can be entered. Would this resolve your problem?

The header that is inserted in the email is done by spamassassin, not by zimbra. You can search for Spamassassin documentation on that.

I happened across another thread after my last post that you need to remember if you change your header, as opposed to simply adding another custom header to what's already there. If I correctly understand the thread (insiders can correct me), the X-Spam-Flag header is what Zimbra uses to determine if you're looking at spam that is going to the Junk folder or not.

So, if you change your spam header, you have to let Zimbra know that it's different or it won't know how to handle the spam messages

At the command line as the zimbra user, type

zmprov gacf | grep zimbraSpamHeader

and you'll see the X-SPAM header that you're already getting. zmprov mcf would then allow you to change those options to match your new headers (but I'd recommend backing up your /opt/zimbra/conf/spamassassin folder first in case you blow something up)

Christian, you can modify the subject (as dwmtractor suggested) but I'm not sure you can (read : "are allowed by the RFC") to add a line inthe headers that does not begins by X-something.

What exactly would you like to get ?

Yes, I know that.

I am not an expert at that, but why is this so? The header I want (see below) seems perfectly valid and is defined.

I would like to get "Precedence: junk". The reason is that I forward mail to another mailserver (exchange) and the header-line will make it stop trying to reply to spam.
