Configuring vSMTP

vSMTP, by default, stores it’s configuration in the /etc/vsmtp directory. Lets look at how files are organized.

Overview

A typical vSMTP configuration looks like the following.

/etc/vsmtp
┣ vsmtp.vsl
┣ filter.vsl
┣ conf.d/
┃     ┣ config.vsl
┃     ┣ interfaces.vsl
┃     ┗ app.vsl
┣ domain-available/
┃     ┗ example.com/
┃           ┣ config.vsl
┃           ┣ incoming.vsl
┃           ┣ outgoing.vsl
┃           ┗ internal.vsl
┣ domain-enabled/
┃     ┗ example.com -> /etc/vsmtp/domain-available/example.com
┣ objects/
┃     ┗ net.vsl
┣ services/
┃     ┗ mysql-service.vsl
┗ plugins/
      ┗ vsmtp-plugin-mysql.so -> /usr/lib/vsmtp/libvsmtp-plugin-mysql-1.0.0.so
