opensmtpd-table-socketmap - 1.1.1-1+b1 main

This package provides the socketmap table for OpenSMTPD. The table may be used
for any kind of key-based lookup by smtpd(8). Socketmap tables use a simple
protocol: the client sends a single-line request and the server sends a
single-line reply.
.
Tables are used by smtpd(8) when authenticating a user, when user information
such as user-id and/or home directory is required for a delivery, when a
domain lookup may be required, and/or when looking for an alias.
