Small, fast and secure yet powerful IMAP webmail

Hastymail2 is a full featured IMAP/SMTP client written in PHP. Our goal is to create a fast, secure, compliant web mail client that has great usability. Hastymail2 is much more lightweight than most popular web based mail applications but still maintains a competitive feature set. The project originated as Hastymail in 2002, then was nearly completely rewritten as Hastymail2 starting in January of 2008. We are very near our first stable release of the second generation of Hastymail and development continues to be active.
