Panda IMAP Home Page

We have received inquiries about continued support of UW imapd (which we wrote) now that the University of Washington has discontinued its IMAP and Alpine development efforts.

Panda Programming has forked the IMAP toolkit from the final University of Washington version (imap-2007b) for internal use. The current UW version is imap-2007e which has only minor changes from imap-2007b; all of these changes (or something better) are in Panda IMAP.

The current version of Panda IMAP is imap-2010.

We are still working on a funding model for Panda IMAP that will permit an public open source distribution. Future development will depend upon internal needs and cost recovery.
