postfix AVCs

[fedora at synersoft.be]

Hello All,

Using targeted policies 1.27.1-2.18 with postfix-2.2.2-2 on FC4.

I receive lots of AVCs related to postfix (here is one regarding postdrop, but 
I have also 'sendmail.postfix', 'cleanup' and 'spamc' related AVCs) :

type=AVC msg=audit(1139803214.270:14817): avc:  denied  { getattr } for

Any explanation ?

If a known bug, could someone post a working postfix.fc/postfix.te set ?

TIA
