Many browsers, such as Netscape and IE, are SSL-enabled, but because the current distribution versions of UW and Cyrus servers do not support SSL, the users can’t take advantage of their browser’s SSL support. There is, however, a workaround—you can use the freely available OpenSSL SSL toolkit and stunnel, an SSL encryption wrapper, to wrap IMAP in SSL. The procedure for adding SSL support to IMAP is documented in this appendix. It involves downloading some free software, building and installing it, generating a certificate, and modifying your inetd configuration.

UW 2000 and the 2.0 release of Cyrus will support native SSL and are expected to be released before this book is published.
