Policy Daemon snapshot-200805071309 (2.x (Cluebringer) branch)
05-07-2008
Policyd v2 (codenamed "cluebringer") is a multi-platform policy server for popular MTAs. This policy daemon is designed mostly for large scale mail hosting environments. The main goal is to implement as many spam combating and email compliance features as possible while at the same time maintaining portability, stability, and performance. Its features include detailed policy and group specification, access control, helo/ehlo checks (helo randomization prevention and RFC compliance), SPF checks, Greylisting, Quotas, and Amavisd-new integration.License: GNU General Public License (GPL)Changes:|

DBD::Gofer::Policy::Base(3) User Contributed Perl Documentation DBD::Gofer::Policy::Base(3) NAME
DBD::Gofer::Policy::Base - Base class for DBD::Gofer policies SYNOPSIS
$dbh = DBI->connect("dbi:Gofer:transport=...;policy=...", ...) DESCRIPTION
DBD::Gofer can be configured via a 'policy' mechanism that allows you to fine-tune the number of round-trips to the Gofer server. The policies are grouped into classes (which may be subclassed) and referenced by the name of the class. The DBD::Gofer::Policy::Base class is the base class for all the policy classes and describes all the individual policy items. The Base policy is not used directly. You should use a policy class derived from it. POLICY CLASSES
Three policy classes are supplied with DBD::Gofer: DBD::Gofer::Policy::pedantic is most 'transparent' but slowest because it makes more round-trips to the Gofer server. DBD::Gofer::Policy::classic is a reasonable compromise - it's the default policy. DBD::Gofer::Policy::rush is fastest, but may require code changes in your applications. Generally the default "classic" policy is fine. When first testing an existing application with Gofer it is a good idea to start with the "pedantic" policy first and then switch to "classic" or a custom policy, for final testing. POLICY ITEMS
These are temporary docs: See the source code for list of policies and their defaults. In a future version the policies and their defaults will be defined in the pod and parsed out at load-time. See the source code to this module for more details. POLICY CUSTOMIZATION
XXX This area of DBD::Gofer is subject to change. There are three ways to customize policies: Policy classes are designed to influence the overall behaviour of DBD::Gofer with existing, unaltered programs, so they work in a reasonably optimal way without requiring code changes. You can implement new policy classes as subclasses of existing policies. In many cases individual policy items can be overridden on a case-by-case basis within your application code. You do this by passing a corresponding "<go_<policy_name">> attribute into DBI methods by your application code. This let's you fine-tune the behaviour for special cases. The policy items are implemented as methods. In many cases the methods are passed parameters relating to the DBD::Gofer code being executed. This means the policy can implement dynamic behaviour that varies depending on the particular circumstances, such as the particular statement being executed. AUTHOR
