email

Email application based on IndieHosters network.

Prerequistes

• docker
• docker-compose

Modify the following files:

• copy env.template to data/config/env and modify it (MYSQL_PASSWORD and DB_ENV_MYSQL_PASSWORD are the same password)

Add the following files:

• data/config/TLS/chain.pem
• data/config/TLS/cert.pem
• data/config/TLS/ssl_certificate.pem
• data/config/TLS/ssl_private_key.pem

If they do not exist a self signed certificate will be created.

Run

./create.sh hostname

Everything should be up and running.

If HTTPS should run on a different port add it as a second argument:

./create.sh hostname 8443

Backup

To backup, just run the BACKUP in your folder, supplying a target path and password. This will create an encrypted duplicity backup.

./BACKUP /some/target/path super-secure-password

Listing available backups

./LIST_BACKUPS /some/target/path

Restore a backup

To restore the latest backup:

./RESTORE /some/target/path super-secure-password now

To restore a specific date list them with LIST_BACKUPS. Example result:

Number of contained backup sets: 2
Total number of contained volumes: 3
 Type of backup set:                            Time:      Num volumes:
                Full         Thu Jan  5 14:07:57 2017                 2
         Incremental         Thu Jan  5 14:35:49 2017                 1

To restore the FULL backup in this example, run:

./RESTORE /some/target/path super-secure-password 2017-01-05T14:07:57
