Friday, 23 February 2007 Mulberry is a high-performance, scalable, and graphically
groovy internet email and calendar client. It uses the IMAP and POP3 protocols
for accessing mail messages on a server, the standard SMTP protocol for sending
messages, and does lots and lots of things with MIME parts for mixed text and
"attachments" of many different types of files and data. It uses WebDAV and
CalDAV for access to server-based calendars, and also invitations to be sent via
email.
