[exim] Spamalerts sent o an specific email address

Hello,

I use an Exim/Spam Assassin /Clamd configuration. So the Exim passes the
mail to the spamd daemon which is listening on localhost on a port.
spamd_address = 127.0.0.1 783
Please can anyone tell me Which configuration need to be made in order to
forward a spam email to a certain email address in order to analyse it if
it's spam indeed.

I know that on another configuration with Postfix/Amavis/SpamAssassin/Clamav
I use $spamadmin (in amavis.conf file) value to do this.

Can you help me please ?

Thank you very much in advance.
Alex,
