<p> The Postfix SMTP server and the remote SMTP client negotiate
a session, which takes some computer time and network bandwidth.
-By default, this session information is cached only in the <a href="smtpd.8.html">smtpd(8)</a>
-process actually using this session and is lost when the process
-terminates. To share the session information between multiple
-<a href="smtpd.8.html">smtpd(8)</a> processes, a persistent session cache can be used. You
+SSLv3, TLSv1 and later support resumption of cached sessions. Not
+is this more CPU and bandwidth efficient, it also reduces latency
+as it uses only one network round-trip instead of two. </p>
+
+<p> Since Postfix uses multiple <a href="smtpd.8.html">smtpd(8)</a> service processes, an in
+memory cache is not sufficient for session re-use. Clients store
+at most one cached session per server and are very unlikey to
+repeatedly connect to the same server process. With a per-process
+server cache, when a client attempts to reuse a session with a
+different process than the one that created it, a new session is
+negotiated and the old forgotten. Returning to the original server
+process later (except with back to back connections) does not help,
+as that session has most probably been replaced. Thus session
+caching in the Postfix SMTP server generally requires a shared cache
+(an alternative available with Postfix ≥ 2.11 is described below).
+</p>
+
+<p> To share the session information between multiple
+<a href="smtpd.8.html">smtpd(8)</a> processes, a session cache database is used. You
can specify any database type that can store objects of several
kbytes and that supports the sequence operator. DBM databases are
not suitable because they can only store small objects. The cache
concurrent access. Session caching is highly recommended, because
the cost of repeatedly negotiating TLS session keys is high.</p>
+<p> Starting with Postfix 2.11, linked with a compatible OpenSSL
+library (at least 0.9.8h, preferrably 1.0.0 or later) the Postfix
+SMTP server supports <a href="http://tools.ietf.org/html/rfc5077">RFC 5077</a> TLS session resumption without
+server-side state when the remote SMTP client also supports <a href="http://tools.ietf.org/html/rfc5077">RFC</a>
+<a href="http://tools.ietf.org/html/rfc5077">5077</a>. The session is encrypted by the server in a <i>session
+ticket</i> returned to client for storage. When a client sends a
+valid session ticket, the server decrypts it and resumes the session,
+provided neither the ticket nor the session have expired. This
+makes it possible to resume cached sessions without allocating space
+for a shared database on the server. This feature can be disabled
+by setting the session cache timeout to zero, otherwise the timeout
+must be at least 2 minutes and at most 100 days. </p>
+
+<p> Note, session tickets can only be negotiated if the client
+disables SSLv2 and does not use the legacy SSLv2 compatible HELLO
+message. This is true by default with the Postfix ≥ 2.6 SMTP
+client. </p>
