Postlite

A set of commands to manipulate a postfix sqlite database. Supports adding users, domains and aliases and creating the DB schema.

Install

1. Clone the repository

   $ git clone https://github.com/bkutil/postlite.git ~/.postlite

2. Make sure ~/.postlite/bin is in your $PATH (use .bashrc on Debian/Ubuntu and .zshrc for ZSH):

   $ echo 'export PATH="$HOME/.postlite/bin:$PATH"' >> ~/.bash_profile

3. Add postlite init to your shell to enable autocompletion.

   $ echo 'eval "$(postlite init -)"' >> ~/.bash_profile

4. Restart the shell

5. Create ~/.postliterc and configure path to your Postfix sqlite DB:

   POSTLITE_DB=/etc/postfix/postfix.db

6. Run postlite db init to create the database and schema

Pre-requisites

Sqlite

Sqlite3 command line client needs to be installed.

Dovecot

doveadm pw is used to hash/prompt for user passwords.

Postfix maps

Postfix needs to be configured to use following virtual maps via main.cf:

sqlite-virtual-alias-maps.cf

dbpath = /etc/postfix/postfix.db
query = SELECT destination FROM virtual_aliases WHERE source='%s'

sqlite-virtual-mailbox-domains.cf

dbpath = /etc/postfix/postfix.db
query = SELECT 1 FROM virtual_domains WHERE name='%s'

sqlite-virtual-mailbox-maps.cf

dbpath = /etc/postfix/postfix.db
query = SELECT 1 FROM virtual_users WHERE email='%s'

Dovecot SQL conf

Dovecot needs to be configured to use sqlite as it's backend and use this password query:

dovecot-sql.conf.ext

driver = sqlite
connect = /etc/postfix/postfix.db
default_pass_scheme = SHA512-CRYPT
password_query = \
  SELECT email as user, password \
    FROM virtual_users WHERE email = '%u'
