Inflate the Dovecot-visible quota to 140% of the configured max_mailbox_size so that Delta Chat clients (which warn at 80% of IMAP-reported quota) never show quota warnings. A quota_warning at 72% of the inflated limit triggers chatmail-quota-expire, which trims the mailbox to 80% of the configured limit. Existing over-quota mailboxes start receiving mail again immediately after deploy without any manual operator action needed.
Chatmail relays for end-to-end encrypted email
Chatmail relay servers are interoperable Mail Transport Agents (MTAs) designed for:
-
Zero State: no private data or metadata collected, messages are auto-deleted, low disk usage
-
Instant/Realtime: sub-second message delivery, realtime P2P streaming, privacy-preserving Push Notifications for Apple, Google, and Huawei;
-
Security Enforcement: only strict TLS, DKIM and OpenPGP with minimized metadata accepted
-
Reliable Federation and Decentralization: No spam or IP reputation checks, federating depends on established IETF standards and protocols.
This repository contains everything needed to setup a ready-to-use chatmail relay on an ssh-reachable host. For getting started and more information please refer to the web version of this repositories' documentation at
