<p><b>Cyrus</b> ist ein <a href="Freie_Software" title="Freie Software">freier</a> <a href="Mailserver" title="Mailserver">Mailserver</a> der <a href="Carnegie_Mellon_University" title="Carnegie Mellon University">Carnegie Mellon University</a>. Ursprünglich wurde die Server-Software für das Campus-Mail-System der Universität entwickelt, mittlerweile ist es jedoch ein anerkannter und auch im professionellen Bereich eingesetzter <a href="Mail_Delivery_Agent" title="Mail Delivery Agent">Mail Delivery Agent</a>. Er unterstützt zurzeit die Protokolle <a href="Internet_Message_Access_Protocol" title="Internet Message Access Protocol">IMAP</a>, <a href="JSON_Meta_Application_Protocol" title="JSON Meta Application Protocol">JMAP</a> und <a href="POP3" class="mw-redirect" title="POP3">POP3</a> und arbeitet mit diversen <a href="Simple_Mail_Transfer_Protocol" title="Simple Mail Transfer Protocol">SMTP</a>-Servern unter Linux/Unix zusammen. Cyrus benutzt die Cyrus SASL Library, eine Implementierung von <a href="SASL" class="mw-redirect" title="SASL">SASL</a>, um mehrere Authentifizierungsmethoden zur Verfügung zu stellen: <a href="CRAM-MD5" title="CRAM-MD5">CRAM-MD5</a>, Digest-MD5, <a href="GSSAPI" title="GSSAPI">GSSAPI</a>, <a href="Einmalkennwort" title="Einmalkennwort">OTP</a>, Plain, <a href="Pluggable_Authentication_Modules" title="Pluggable Authentication Modules">PAM</a>. Von diesen Methoden arbeiten einige mit starker Kryptographie.
