Covers the concepts and practical experiences of IMAP. The book talks a lot about the Cyrus IMAP server, which has Tcl embedded, and the catalog entry above claims that it includes an appendix that covers Tcl.
First edition does not have an Appendix on Tcl. Tcl is part of cyradm, Cyrus administrator program. Many scripts are included as examples.
