Build Docker images

Unofficial imapgrab Dockerfile for backing up all folders of an imap server.

Quickstart

After installing docker, just run the following command:

docker pull maxkratz/imapgrab:latest

Environment variables

You can use the following environment variables for customization of this container:

MAILHOST # Hostname of the imap server
MAILUSER # Login-Name (mailbox)
MAILPASSWORD # Password (mailbox)
MAILFOLDER # Subfolder for creating the backup
MAILLOG # If set to true, container will create a log instead of using console output

Mount volumes or bind folders

One may mount a folder of the host to /mnt within the container to enable persistent backups of imap servers.

  • /mnt/mail will be used as backup target.
  • /mnt/log will be used as log target (if environment variable is set).

Full example command

docker run -it -e "MAILHOST=mail.example.net" -e "MAILUSER=user@example.net" -e "MAILPASSWORD=secure123" -e "MAILFOLDER=mybackup" -e "MAILLOG=TRUE" -v /home/maxkratz/email-backups/:/mnt maxkratz/imapgrab:latest

Creates a backup of all files and folders of the mailbox user@example.net with password secure123 at host mail.example.net inclusive logs into subfolder mybackup.
