We use Digicert here, which uses an intermediate certificate. Our configuration is the same: tls_cert_file: /etc/ssl/certs/file.crt tls_key_file: /etc/ssl/private/file.key tls_ca_file: /etc/ssl/certs/DigiCertCA.crt tls_ca_path: /etc/ssl/certs > I've found a howto on the thawte.nl website > > http://www.thawte.nl/fr/support/manuals/cyrus/cyrus+imap+server/install >+certificate/ > > which puts private key, certification and the intermediate certificate >file in one .pem file and uses this combined file for tls_cert_file, >tls_key_file and tls_ca_file. Good way? We have not had to do that. >4. do I have to remove /var/lib/cyrus/tls_sessions.db ? I don't think so. We've renewed/reinstalled our certificate a couple of times over the years and have not had to do anything but a restart. A restart may not even be necessary if both the old and new certificates are valid, and your imapd sessions cycle out over time (via timeout, or the -U option). -- Dan White ---- Cyrus Home Page: http://www.cyrusimap.org/ List Archives/Info: http://lists.andrew.cmu.edu/pipermail/info-cyrus/
