Goals
Aerogramme design enables the following properties:
-
Privacy friendly
Per-user encryption of mailboxes.
Can be run as a local proxy to hide your mailbox content from the server. -
Easy to operate
Transparently replicate mailbox and solve conflicts.
Integrate with your LDAP server. -
Highly resilient
Multiple instances of Aerogramme can been run in parallel without coordination.
Support datacenter failures.
Roadmap
Aerogramme is currently a technical preview. Following released are planned:
-
⌛0.1.xCorrect parsing of emails. (~june '23).
-
⌛0.2.xSupport of IMAP4rev1. (~september '23).
-
⌛0.3.xSubset of IMAP4rev2. (~december '23).
-
⌛0.4.xCalDAV support. (~february '24).
-
⌛0.5.xCardDAV support.
It works with your email client
Aerogramme integrates into your existing workflow:
Aerogramme implements the IMAP protocol
and thus is already compatible with many applications.

Standing on the shoulders of giants
Aerogramme leverages insights from research & other software:
- Managing update conflicts in Bayou, a weakly connected replicated storage system by Terry et al.
- Designing a Planetary-Scale IMAP Service with Conflict-free Replicated Data Types by Jungnickel et al.
- Technology for Resting Email Encrypted Storage (TREES) used by Rise Up.
- Dovecot Obox Plugin by Open-Xchange.
