The udev denial seems fixed with selinux-policy-targeted-2.0.6-1. So
things get (slowly) fixed. But most issues are still there :

audit2allow < /var/log/audit/audit.log
You should do

audit2allow -l  < /var/log/audit/audit.log

To only get the messages of what AVC messages you got after the last reload.
allow dovecot_auth_t var_lib_t:dir search;
allow system_chkpwd_t devpts_t:chr_file { read write };
allow procmail_t spamd_port_t:tcp_socket name_connect;
allow updfstab_t tmpfs_t:dir getattr;
allow dovecot_auth_t etc_runtime_t:file read;
allow spamd_t port_t:udp_socket name_bind;
(this bit is the spamassassin resolver issue Steven Stern just reported
for FC4. It was briefly fixed in Rawhide, then regressed to broken stage
with the 2.x policy change)

(generated on a clean fully relabeled system after 3 min of activity)

That's almost the same list I had with selinux-policy-targeted-2.0.0

selinux-policy-2.0.6-2 should fix most of those.

This one is much better, right. I had to work a little harder to fill my
AVC quota. Now I only get :

# audit2allow < /var/log/audit/audit.log | sort
allow dovecot_auth_t var_auth_t:dir write;
(on-the-fly pam_abl database creation failure, strangely works fine from
ssh)

allow saslauthd_t self:capability setuid;
(should saslauthd be allowed setuid ?)

allow saslauthd_t var_auth_t:dir search;
(more pam_abl stuff)

allow spamd_t port_t:udp_socket name_bind;

Probably related to one of those :
