This does seem to work but surely there's a tidier way of handling those class requirements? What am I missing?

You want to use the "policy_module(procmail,0.1)" macro instead of the
module statement at the top.  It adds all of the kernel object classes,
so you don't have to write them all out.

Thanks, that's much better:

policy_module(procmail, 0.2)

require {
	type procmail_t;
	type sbin_t;
	type var_log_t;

# Needed for writing to /var/log/procmail.log
allow procmail_t var_log_t:dir search;
allow procmail_t var_log_t:file append;

# ==============================================
# Procmail needs to call sendmail for forwarding
# ==============================================
# This should be in selinux-policy-2.2.34-2 onwards

# Read alternatives link
allow procmail_t sbin_t:lnk_file read;

# Allow transition to sendmail
# (may need similar code for other MTAs that can replace sendmail)

Cheers, Paul.
