Full-text search allows all messages to be indexed, so that mail clients can quickly and efficiently search messages by their full text content.

Overview

The dovecot-solr Plugin is used in conjunction with Apache Solr running in a separate container. This is quite straightforward to setup using the following instructions.

Setup Steps

1. docker-compose.yml:

  solr:
    image: lmmdock/dovecot-solr:latest
    volumes:
     - solr-dovecot:/opt/solr/server/solr/dovecot
    restart: always

  mailserver:
    image: tvial/docker-mailserver:latest
    ...
    volumes:
      ...
      - ./etc/dovecot/conf.d/10-plugin.conf:/etc/dovecot/conf.d/10-plugin.conf:ro
    ...

volumes:
  solr-dovecot:
    driver: local

2. etc/dovecot/conf.d/10-plugin.conf:

mail_plugins = fts fts_solr

plugin {
  fts = solr
  fts_autoindex = yes
  fts_solr = url=http://solr:8983/solr/dovecot/ 
}

3. Start the solr container: docker-compose up -d --remove-orphans solr

4. Restart the mailserver container: docker-compose restart mailserver

5. Flag all user mailbox FTS indexes as invalid, so they are rescanned on demand when they are next searched

docker-compose exec mailserver doveadm fts rescan -A
