What it does
NeoMutt is a separately maintained terminal email client derived from Mutt. Its documentation covers PGP, S/MIME, Autocrypt and encrypting copies to the sender.
NeoMutt’s encryption documentation is organized around concrete setup tasks: PGP, S/MIME, Autocrypt and keeping a decryptable copy for the sender. That is useful for a terminal user who wants to understand the configuration rather than rely on an unexplained encryption toggle.
The project describes itself as a Mutt fork with added features and maintains its own releases and guide. It remains an email client, so mailbox hosting and key-management decisions are separate responsibilities. Consult the current guide for the specific encryption backend and workflow instead of assuming a configuration copied from another Mutt-based client will be identical.
Strengths
- The guide separates several encryption and signing setup tasks.
- The project maintains its own releases and documentation.
Best for
- Terminal-mail users who need configurable standard encryption workflows
