Panda IMAP is a server that implements the Internet Message Access Protocol (IMAP) version 4 revision 1. It is a fork of a fork: The late Marc Crispin wrote the initial implementation which become known as "UW IMAP". He forked the code base in 2008 and called the fork "Panda IMAP". After development ceased, I forked the fork but kept the name. I maintain the public master branch at https://github.com/sequenced/panda-imap
