Local user marked as spammer


I am running postfix + amavis + clamav + spamassassin on my mail server. Today I got a complaint from my director asking why a mail sent from one of our employees was marked spam when he received it. I found my log files as :

Quote:
Oct 28 15:11:08 MYHOST amavis[11669]: (11669-14) ESMTP::10024 /var/amavis/tmp/amavis-20091028T144544-11669: <employee@MYDOMAIN.com> -> <director@MYDOMAIN.com> SIZE=2601 Received: from MYHOST.MYDOMAIN.com ([127.0.0.1]) by localhost (MYHOST.MYDOMAIN.com [127.0.0.1]) (amavisd-new, port 10024) with ESMTP for <director@MYDOMAIN.com>; Wed, 28 Oct 2009 15:11:08 -0700 (PDT)

I don't get a clear idea of the logs. Can someone explain why this happened and how can I avoid this to happen in future?

Thanks.

Another thing i found :

If the mail is sent from outlook through our corporate network, it is marked as spam. But a mail sent thru the webmail (we use squrrelmail), it comes without any spam flag !!!!

Is there anyway to add my corporate network as trusted in spamassassin, so that it will not flag my local users as spam ?

You can add in local.cf
Code:
trusted_networks 192.168.0.0/24
or whatever your LAN ip range is.
