Horde Groupware is an enterprise ready browser-based collaboration suite. Users can manage and share calendars, contacts, tasks, and notes with the standards compliant components from the Horde Project. Horde Groupware bundles the separately available applications Kronolith, Turba, Nag, and Mnemo. It can be extended with any of the released Horde applications or the Horde modules that are still in development, like a file manager, a bookmark manager, a forum, or a wiki.
XPertMailer is a PHP class that you can use to send encoded MIME type e-mail messages (text, HTML, HTML embedded images, attachments) towards a client or relay SMTP server with optional authorisation and TLS/SSL support. Cc and Bcc functionality is included. The class functions are optimised to execute in a very small time and to be easy to use. The data sending is done according to RFCs 821, 822, 2821, 2822, and 2487, and the message type conforms with RFCs 2045, 2046, 2047, 2048, and 2049.
