Description of problem:
SELinux blocks postfix from delivering messages to cyrus using the lmtp
protocol. I'm having these messages in the audit.log :

type=AVC msg=audit(1163615289.186:35044): avc:  denied  { search } for  pid=738

subj=user_u:system_r:postfix_smtp_t:s0 key=(null)

Version-Release number of selected component (if applicable):
selinux-policy-targeted-2.4.3-2.fc6

How reproducible:
Always

Additional info:
I did a fixfiles relabel and restarted postfix and cyrus-imapd to make sure. I
still have the problem.
The distribution is an FC5 yum-upgraded to FC6, but the "fixfiles relabel"
should have taken care of labeling problems
