Description of problem:

The SELinux targetted policy doesn't allow for postfix/mailman integration
using the postfix pipe transport.  The rules in postfix.te only allow
postfix pipe to transition to procmail, but not to mailman or python.
(The most common method of postfix/mailman integration is using a python
script postfix-to-mailman.py.)

Until this is fixed, I can't run my server in enforcing mode, because none
of the mailing lists will work.

Version-Release number of selected component (if applicable):

selinux-policy-targeted-1.27.1-2.22 (FC4)
selinux-policy-2.2.15-4 (FC5test3)

How reproducible:

100%

Steps to Reproduce:
1.  Set up targeted or strict SELinux policy with enforcing turned on
2.  Install postfix and mailman
3.  Install postfix-to-mailman.py script
4.  Update /etc/postfix/main.cf, /etc/postfix/master.cf, and
/etc/postfix/trasnport per the postfix-to-mailman.py instructions
5.  Run postmap on /etc/postfix/transport to update /etc/postfix/transport.db
6.  Create a mailing list in mailman
7.  Send email to the mailing list submission address
8.  /var/log/maillog will show that the postfix-to-mailman.py script failed to
execute.  /var/log/audit/audit.log will show that SELinux blocked the invocation
of the script due to the postfix_pipe_t policy.
  
Actual results:

Postfix pipe can't deliver email to mailman via the python script

Expected results:

Postfix pipe should deliver email to mailman via the python script
