+===== Email Related Guidelines =====
+**CUNI Guideline – Use of private e-mail addresses**: [[https://cuni.cz/UKEN-907.html|EN version]] / [[https://cuni.cz/UK-9142.html|CZ version]]
+In principle:
+ <font inherit/inherit;;#d35400;;inherit>NO PRIVATE EMAIL FOR OFFICIAL COMMUNICATION IS ALLOWED</font>
+**…o**//**nly work e-mail accounts **under institutional domain **may be used for employees to send work e-mail **messages at institution, to send e-mail messages to students, and any other communication at institutuin, as well as sending e-mail messages to third parties. With respect to the GDPR, it is not admissible to use private e-mail accounts or accounts at other organizations to send work e-mail messages, to communicate with students, to handle the official administrative agenda, etc.//
+Conclusion: If you get work email from non-institutional email address (like google.com, seznam.cz, post.de, outlook.com, yahoo.com etc.) you should take it as a potential fake email. Every employee and student at institutuon has his/her own institutional email address so it may be expected to get emails from such addresses, not from freemail etc.
