Thanks for your response.

Unfortunately, Flash is hard-wired to connect to 843 when looking for a socket policy file. If it fails to find a server on that port, it will try to find a policy file on the port it is trying to connect to, so you can build policy file handling into your application. This doesn't really work for me as I have written an AMF3-based protocol for my application server and to get a string that says "<policy-file-request>" rather than a 4-byte length indicator makes things pretty complicated.

That approach you describe sounds like something I eventually must do. I'd like the policy server daemon to be like Apache or MySQL in that it starts up when the machine reboots -- so you don't have to manually start it, etc.

Can you point me toward any resources which might explain how I could set up my script as a startup daemon which runs as root and then relinquishes its permissions?

POSTFIX-ADD-POLICY(8)					      System Manager's Manual					     POSTFIX-ADD-POLICY(8)

NAME

       postfix-add-policy - add policy service to Postfix master.cf

SYNOPSIS

       postfix-add-policy [policy name...] [username...] [argv...]

DESCRIPTION

       The  postfix-add-policy(8)  command  adds  an  smtp  policy server named policy name running using username and called as argv to etc/post-
       fix/master.cf to facilitate integration of SMTP policy servers such as postgrey or postfix-policyd-spf-perl.  The configuration is based on
       the Postfix SMTPD_POLICY_README.  Adminstrators should verify it is appropriate for their requirements.

       The original file is copied prior to modification and left in /etc/postfix to make it possible to revert changes easily.

       Available in the Debian package for Postfix version 2.5.3 and later.

DIAGNOSTICS

       If the given policy name  already appears in the master.cf, a message will be printed to standard out and master.cf will not be modified.

ENVIRONMENT

       MAIL_CONFIG
	      Directory with Postfix configuration files.

	      The  postfix-add-policy(8)  command  should  use	this, but it currently doesn't.  It is hard coded to /etc/postfix.  This should be
	      changed.

CONFIGURATION PARAMETERS

       None

FILES

       /etc/postfix/master.cf

       postconf(5), Postfix configuration
