Pegasus Mail and Pagkugi

Long-lived, single-developer local mail client, still maintained.

At a glance

A deep rules system, conservative HTML, raw message inspection, a local user-controlled store, and offline-first operation.

Where Pagkugi differs. Its plain-text honesty and local control are close to Pagkugi's, but it keeps mail in its own store and bundles a mail server rather than using open Maildir storage and composed tools.
