Some of these may be implemented as automatic procedures to limit abuse. Some may be detected manually. These rules are in addition to the rules for computer use found in <a href="/rules/en/OC5_english.pdf">OC5</a>.</p> <h4>Rules</h4> <p>Users of the mail services must not: </p> <ul> <li>Send mail bombs – sending the same mail to thousands of people individually. You should use an official mailing list. </li> <li>Send mail SPAM – unsolicited mail, for advertising purposes</li> <li>Send chain letters, forge mail messages or news articles</li> <li>Send offensive or insulting e-mails. </li> </ul> <h4>Privacy </h4> <p>As outlined in <a href="/rules/en/OC5_english.pdf">OC5</a> it is regarded as an abuse of the CERN computing facilities for persons to attempt to access other users' data. Users of the mail system should nevertheless be aware that there can be no guarantees given concerning the privacy of dispatched e-mail. Misaddressed or poorly addressed mail may be delivered to the wrong person or be handled by an unknown postmaster at another site. </p> <p>CERN gives no undertaking to <i><b>guarantee</b></i> the privacy of e-mail. </p> <p>In order to ensure the smooth functioning of the service, CERN grants the administrators of the Mail service the right to intercept e-mail messages and examine any e-mail communications at any time, in the course of performing their duties as administrators of the Mail service. </p> </div>    <div id="sidebar"> <h3>CERN Computing Rules</h3> <ul class="sidemenu"> <li><a href="/rules/en/OC5_english.pdf">Operational Circular Nº5</a></li> <li><a href="/rules/en/oc5_aims.shtml">Aims of OC5</a></li> <li><a href="/rules/en/personal_use_policy.shtml">Personal use policy</a></li> <li><a href="/rules/en/violation_of_rules.shtml">Violation of rules</a></li> <li><a href="/rules/en/CERN_Cybersecurity_Policy_v1.2.pdf">Cybersecurity Policy</a></li> <li><a href="/rules/en/CERN_CSO_Mandate_v1.1.pdf">Mandate of the CSO</a></li> <li><a href="/home/en/CERN/liaisons.shtml">Departmental & Experiment Liaisons</a></li> <li><a href="/rules/en/board.shtml">Computer Security Board</a></li> </ul> <h3>OC5 Subsidiary Rules</h3> <h3>& Guidelines</h3> <ul class="sidemenu"> <li><a href="/rules/en/accounts.shtml">Computer accounts</a></li> <li><a href="/rules/en/dhp.shtml">Data Handling Policy</a></li> <li><a href="/rules/en/drp.shtml">Data Retention Policy</a></li> <li><a href="/rules/en/firewall.shtml">Outer Perimeter Firewall Openings</a></li> <li><a href="/rules/en/ddp.shtml">Properly destroying data</a></li> <li>Protecting files on <a href="/rules/en/afs.shtml">AFS</a>, <a href="/rules/en/dfs.shtml">DFS</a> and <a href="/rules/en/eos.shtml">EOS</a></li> <li><a href="/rules/en/windows.shtml">Running Windows PCs</a></li> <li><a href="/rules/en/baselines.shtml">Security Baselines</a></li>  <li><a href="https://admin-eguide.web.cern.ch/en/procedure/social-media-guidelines">Social Media Guidelines</a></li> <li><a href="/rules/en/data_access_by_thirds.shtml">Third party access to users' accounts and data </a></li> <li><a href="/rules/en/file-services.shtml">Using file services</a></li> <li><a href="/rules/en/mail-service.shtml">Using the e-mail service</a></li> <li><a href="/rules/en/network.shtml">Using the network</a></li> <li><a href="/rules/en/webcams.shtml">Using webcams</a></li> </ul> <h3>Software Restrictions</h3> <ul class="sidemenu">   <li><a href="/rules/en/otp-generators.shtml">OTP Generators</a></li>   <li><a href="/rules/en/teamviewer.shtml">TeamViewer</a></li>  <li><a href="/rules/en/vpn.shtml">VPNs and other overlay networks</a></li> </ul> <h3>Other Useful Information</h3> <ul class="sidemenu"> <li><a href="https://indico.cern.ch/category/3441">Licensing CERN Software</a></li> <li><a href="https://odpp.web.cern.ch/">Office of Data Privacy Protection</a></h3> <li><a href="http://www.ohwr.org">Open Hardware Repository</a></h3> </ul> </div>   </div>  <div id="footer-wrap"> <div id="footer-bottom"> © Copyright 2024<strong> <a href="https://cern.ch/security">CERN Computer Security Office</a></strong> <table> <tr> <td id="footer-info-left"> e-mail: <a href="mailto:Computer.Security@cern.ch">Computer.Security@cern.ch</a><br/> Please use the following PGP key to encrypt your messages:<br/> ID: 0x954CE234B4C6ED84<br/> <a href="https://keys.openpgp.org/vks/v1/by-fingerprint/429D60460EBE8006B04CDF02954CE234B4C6ED84">429D 6046 0EBE 8006 B04C DF02 954C E234 B4C6 ED84</a> </td> <td id="footer-info-right"> Phone: +41 22 767 0500<br/> Please listen to the recorded instructions. </td> </tr> </table> </div> </div>  </div>   </body> </html>
