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 SEE ALSO
postconf(5), Postfix configuration LICENSE
