The Infotrope ACAP Server is an implementation of RFC2244, complete with asynchronous notification of changes, stored search results, ACLs, and data inheritance, etc. It supports TLS and SASL encryption as well as the entire base standard, plus a few optional extensions. ACAP allows applications to store configuration data in a way that is standard, fully interoperable, and easily managed by users, administrators, and technical support teams alike. Infotrope's key features include the ability to randomly crash the server without data loss, and backing up of data (even while it's being written) without losing integrity.
Infotrope Polymer is a fully roaming online IMAP client. You can roam with your full configuration, your addressbooks, and even your bookmarks. It's fully ACAP enabled, and will operate with or without a local disk cache, and over very narrow connectivity (like GPRS), using minimal bandwidth. It supports the majority of extensions to ESMTP, IMAP, and ACAP, whether in RFC or I-D.

Now also available as public-acap.dave.cridland.net, which resolves in both IPv6 and IPv4.
To add to the tiny list of ACAP-enabled software, there's Infotrope Polymer released vaguely properly, too, over at /projects/polymer.
