prayer

standalone IMAP-based webmail server

Prayer is yet another Webmail interface. It is unusual in that it is a complete, standalone, HTTP server and proxy rather a Apache/mod_php plugin. Prayer maintains persistent connections to the IMAP server and is written entirely in C. Consequently it is much faster than most open source Webmail interfaces and puts very little load on either the machines running the Web server or the backend IMAP servers (even if traditional Unix format mailfolders are in use). Prayer has very few external dependencies as user preferences are stored on the IMAP server rather than in a SQL database. It does however implement a full range of features and user preference settings.
