+# installs a self-signed certificate.  This is useful for testing, but you
+# should obtain a real certificate from a recognized certificate authority.
+#
+# These files are opened before dropping root privileges, so keep the key file
+# unreadable by anyone but root. Included /usr/share/dovecot/mkcert.sh can be
+# used to easily generate self-signed certificate, just make sure to update the
+# domains in dovecot-openssl.cnf
