Mail from Outside our Domain not Stored

[Lamar Milligan]

Email from outside our domain are not stored in the quarantine folders. 
If email originates from our domain it is processed as expected, both
stored and delivered to recipients.  MailScanner runs on a mail gateway
running sendmail.  All users have entries in the /etc/aliases file that
actually delivers email to accounts on our Zimbra server.  I suspect that
is the reason for this behavior, but would really appreciate input from
others. 

The following are set in the MailScanner.conf file:
Spam Actions = store header "X-Spam-Status: Yes"
High Scoring Spam Actions = store header "X-Spam-Status: Oh Yes"
Non Spam Actions = store deliver header "X-Spam-Status: No"

Thanks for your help,
