The Database Schema
The slowmilt milter uses Berkeley DB 4.2, which is not
a relational database. Although two databases can be joined for bidirectional
lookups, that approach was not used for slowmilt.
The slowmilt milter uses a single database:
The keys for the IP address database are IP addresses stored
in binary in standard network byte order.
For version 3 of the database duplicate keys are allowed so all entries
are grouped by IP number keys.
The data for the database is a structure that looks like
The items in this datum structure (together) define a single event.
See the standard event set for a
description of what the items in this structure mean. Also see
slow.h in the source distribution to understand the ordering
of bits in
can be dumped to a file using the
slowedit list command, and that text
output can be later be fed back into the
slowedit rebuild command
to recreate the database.
