This means one process per connection. So when there are multiple
smtpd(8) processes, each one will spawn a separate policy service.
The policy service should exit once smtpd(8) disconnects.

I would be very surprised if actual zombie processes were involved. The
spawn(8) services waits for its child process, and master(8) waits for
its child spawn(8) processes, so if there are zombie processes, they are
perhaps because your script forks a subprocess and does not collect its
status in a timely manner.
I really would not recommend PHP by the way. Try Python, Perl or Ruby.
