<p><span class="application">Cone</span> is a text-based mail
client. <span class="application">Cone</span> seamlessly
handles multiple POP3, IMAP accounts, and local mail folders.
<span class="application">Cone</span> is also a simple
newsreader. <span class="application">Cone</span>'s interface
is foolproof enough to be used by inexperienced users, but it
also offers advanced features for power users.</p>

<ul type="disc">
<li>
<p>An online tutorial provides a quick overview of
<span class="application">Cone</span>'s main
features.</p>
</li>
<li>
<p>A built-in <a class="link" href="leaf.html" title="leaf" shape="rect">text editor</a> for editing new
messages, with search/replace and spell checking
(requires <span class="command"><strong>aspell</strong></span> or
<span class="command"><strong>pspell</strong></span>).</p>
<p>Shortcuts - assign frequently used text to a
function key, or to an abbreviation. Insert the text
by pressing the function key or typing its
abbreviation.</p>
</li>
<li>
<p>Supports UTF-8 consoles (requires the
wide-character version of the curses library).</p>
</li>
<li>
<p>Displays HTML mail, with automatic de-moronization
(“<span class="quote">smart
quotes</span>”, and similar clutter, is
replaced by plain garden-variety punctuation).</p>
</li>
<li>
<p>Displays attached images, if invoked from an X
terminal, by running Gnome's <span class="command"><strong>eog</strong></span>, or KDE's
<span class="command"><strong>kview</strong></span>
image viewer. Displays <code class="literal">PDF</code> attachments by running
<span class="command"><strong>xpdf</strong></span>.
Other, or alternative, helper applications will be
added as time permits.</p>
</li>
<li>
<p>After attachments are downloaded, they can be
optionally removed from the message.</p>
</li>
<li>
<p>Handles local mail folders, maildirs, IMAP and
POP3 accounts, and Usenet newsgroups. All folders are
shown in a hierarchical tree-like display.</p>
</li>
<li>
<p>Supports access to servers through a Socks 5
proxy, using the Courier Socks 5 API toolkit.</p>
</li>
<li>
<p>Sends mail using an external SMTP server
(with/without authentication), or the local
<span class="command"><strong>sendmail</strong></span>
command.</p>
</li>
<li>
<p>All network protocols support SSL/TLS and SASL
(CRAM-MD5, CRAM-SHA1, and LOGIN).</p>
</li>
<li>
<p>Optional authentication using client SSL
certificates.</p>
</li>
<li>
<p>Address books (which can be stored in an IMAP
folder).</p>
</li>
<li>
<p>Optional support for LDAP address books.</p>
</li>
<li>
<p>Remote configuration (share a common configuration
between different instances of <span class="application">Cone</span>).</p>
</li>
<li>
<p>An optional “<span class="quote">single
sign-on</span>”. Use a single master password
for multiple remote mail server accounts.</p>
</li>
<li>
<p>PGP/GPG based encryption, and digital signatures.
Sent messages are automatically signed. Different
signing keys may be selected for different mail
accounts, and the appropriate key is automatically
selected when replying to a message from an account.
Selecting a message for an encryption automatically
looks up keys that match the recipients' E-mail
addresses.</p>
<p>Import, export, forward and receive PGP/GPG keys
as MIME attachments.</p>
<p>When a single sign-on master password is
installed, the master password also handles access to
passphrase-protected keys.</p>
</li>
<li>
<p><span class="application">Cone</span> shares a lot
of its code base with the <a class="ulink" href="http://www.courier-mta.org" target="_top" shape="rect">Courier mail server</a>, which is why they
share the same web site together.</p>
</li>
<li>
<p><span class="application">Cone</span> also serves
as a platform for development of a new experimental
network mail access protocol, <a class="link" href="smap1.html" title="Appendix A. Simple Mail Access Protocol, Version 1" shape="rect">SMAP</a>, that offers additional
functionality not available with IMAP or POP3. When
<span class="application">Cone</span> logs on to a
SMAP-capable server, such as the current development
version of Courier, additional features become
available:</p>
<div class="orderedlist">
<ol type="1">
<li>
<p>Folder names may utilize the full UTF-8
character set, without any reserved folder
hierarchy separator characters. The user does
not need to be aware of the underlying mail
folder implementation.</p>
</li>
<li>
<p>Faster downloading of attachments.</p>
</li>
<li>
<p>Faster mail sending. SMAP does not require
the client to open a second SMTP connection,
and send a second copy of the message via
SMTP.</p>
</li>
<li>
<p>Fast opening of large folders. <span class="application">Cone</span> does not need to
download the complete folder index every time
the folder is opened, only what's changed to
the folder since the last time it was open.</p>
</li>
<li>
<p>Many other useful features that are waiting
to be implemented.</p>
</li>
</ol>
</div>
</li>
<li>
<p><span class="application">Cone</span> owes its
versatility in handling a large variety of mail
protocols to the fact that it's based on <a class="link" href="libmail.html" title="LibMAIL reference" shape="rect"><span class="application">LibMAIL</span></a> , a generic C++
library that provides a high-level mail-handling API.
Using the <code class="literal">--with-devel</code>
configuration setting installs the <span class="application">LibMAIL</span> toolkit, which allows
for development of independent E-mail software.</p>
