USE WHAT YOU KNOW

atmail store(obj) is for open source Dovecot email server and supports multiple cloud storage and cluster filesystem vendors.

Features


COMPATIBLE

Support for various Cloud Storage or Cluster Filesystem Vendors. Currently supporting AWS S3. Soon to be supporting Ceph, OpenIO, DreamObjects, Backblaze and Scality.

DE-DUPLICATION SUPPORT

A 1 MB PDF attachment sent to 10 local users, traditionally stored 10 times (once for each recipient) on local disk, is stored once with atmail store(obj).

COMPRESSION SUPPORT

Each de-duplicated attachment can be compressed before storing it on any of the supported cloud storage services and platforms.

CACHE SUPPORT FOR BANDWIDTH OPTIMISATION

MIME attachments that are fetched from the cloud storage are cached locally (REDIS and local Filesystem) to ensure a responsive user experience.

FLEXIBLE ADMINISTRATION

  • Your administrator can choose which attachments will be uploaded to cloud storage based on multiple parameters such as the date the email was received, the size of the attachment or various email attributes.
  • Use one command line to interact with multiple cloud storage providers.

How It Works


Dovecot Core reads index files and fetches email from (a). Fetch requests for MIME attachments are sent to the atmail plugin. atmail store(obj) attempts to fetch from (a), (b) or (c) in that order. If the attachment is not found on (b), the plugin caches this for future fetches.
