Mail::MtPolicyd::Plugin::Honeypot - mtpolicyd plugin for creating an honeypot


version 2.03


The Honeypot plugin creates an honeypot to trap IPs sending to unused recipient addresses.

The plugin requires that you define unused recipient addresses as honeypots. These addresses can be specified by the recipients and recipients_re parameters.

Each time an IP tries to send an mail to one of these honeypots the message will be reject if mode is 'reject' and an scoring is applied. The IP is also added to a temporary IP blacklist till an timeout is reached (parameter expire). All IPs on this blacklist will also be rejected if mode is 'reject' and scoring is applied.
