asgard is a suite of modules based on email workflow.

hermodr (hermóðr, the messenger) forwards messages from IMAP inbox to another address; it’s designed to be used with https://github.com/emersion/hydroxide[hydroxide].

mimir (Mímir, renowned for his knowledge) is a client-side topic-based mailing list and archive; it acts as a mailing list, forwarding messages based on their In-Reply-To header, and stores them in public archive. Best used as a companion to an open source project.

tyr (Týr, valorous and powerful) is an address-based filter; it lets messages pass through if the pair (sender, recipient) is allowed, directs messages to junk if the pair is explicitly not allowed, and sends a notification to sender if the pair is not known.

vor (Vör, associated with wisdom) is a client-side address-based mailing list. It forwards messages sent to a specific address to all interested parties.
