On a related matter, I sometimes like to use a system-wide procmail 
script (/etc/procmailrc) and have system-wide procmail logs to go with 
that, which can be done by putting in /etc/procmailrc something like:

LOGFILE=/var/log/procmail.log
or
LOGFILE=/var/log/procmail/$LOGNAME

Current policy doesn't cater for this, so I added:

::::::::::::::
myprocmail.te
::::::::::::::
policy_module(myprocmail, 0.5.6)

require {
        type procmail_t;
        type sendmail_t;
};

# log files
type procmail_log_t;
logging_log_file(procmail_log_t)

# Write log to /var/log/procmail.log or /var/log/procmail/.*
allow procmail_t procmail_log_t:dir setattr;
create_files_pattern(procmail_t,procmail_log_t,procmail_log_t)
append_files_pattern(procmail_t,procmail_log_t,procmail_log_t)
read_lnk_files_pattern(procmail_t,procmail_log_t,procmail_log_t)
logging_log_filetrans(procmail_t,procmail_log_t, { file dir })

# ==============================================
# Procmail needs to call sendmail for forwarding
# ==============================================

# Read alternatives link (still not in policy?)
corecmd_read_bin_symlinks(procmail_t)

# Procmail occasionally signals sendmail, e.g. when it times out during 
forwarding
sendmail_signal(procmail_t)

::::::::::::::
myprocmail.fc
::::::::::::::
/var/log/procmail\.log  -- 
gen_context(system_u:object_r:procmail_log_t,s0)
/var/log/procmail(/.*)? 
gen_context(system_u:object_r:procmail_log_t,s0)





The last bits of policy are things I've had locally for a couple of 
Fedora releases now; not sure if they're in current policy but I think 
they should be.

Cheers, Paul.
