Multi-line RBL rejection notices

Downloadable Software

Description

The rbl-multi-milter sendmail milter is a configurable sendmail plugin that both contacts a list of RBLs (Realtime Blackhole List) and maintains an internal white/black list in a configuration file. When users are rejected the milter can send a different multiline error response for each configured RBL.

rbl-multi-milter does not rely on sendmail 8.13's milter api support for multi-line replies and therefore works with 8.12 as well.

Background

More information on sendmail milters

This milter is based on Jeremy Beker's rbl-milter 0.30. It has been created with the primary motivation of returning multiple line error messages to spamming clients.

Significant changes made are as follows:
  • RBL'd messages are rejected, not marked then accepted.
  • Multiple line error messages can be returned.
  • RBLs and a rejection message are stored in a conf file.
  • White and black lists are stored in the conf file.
