Sounds like you are running a similar setup to us (though we're on a 10.4.5 server) -- you may want to check the headers on those outbound emails and make sure spamassassin and clam are even screening it -- I'm assuming you're using smtp for your outbound mail, not the php method in the files.
Also, if you're on an OS X server, note that there are known issues with spamassassin not training well, and ignoring headers -- if you require documentation on this, let me know.

Hello all of you.
I have notice something weared I would like to share with you. I have installed a postfix server doing antispam and antivirus content filter (using spamassassin & content_filter and clamav&clamsmtpd) Everything is ok except when I'm writing an email from roundcube webmail I tested writing an email attaching the eicar virus test file and when I send it the email scanner says there is no virus in the message! I did the same test with 2 others webmail and the virus has been discovred by clamd!
Do you have any clues?
