POSTFIX-ADD-FILTER(8) System Manager's Manual POSTFIX-ADD-FILTER(8)NAME
postfix-add-filter - add filter service to Postfix master.cf
SYNOPSIS
postfix-add-filter [smtp service name...] [smtpd port...]
DESCRIPTION
The postfix-add-filter(8) command adds an smtp service named smtp service name and and smtpd server listening on smtpd port to etc/post-
fix/master.cf to facilitate integration of SMTP filters such as amavisd-new or clamsmtp. The configuration is based on the upstream recom-
mendations for amavisd-new 2.6.0. 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 smtp service name or smtpd port already appear 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-filter(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
