There are two Email systems in NSU:

• The first is intended mainly for students and teachers; it serves addresses in the g.nsu.ru, alumni.nsu.ru and non-employee.nsu.ru domains (that is, addresses like i.ivanov@g.nsu.ru, i.ivanov@alumni.nsu.ru, i.ivanov@non-employee.nsu.ru) and is based on G Suite for Education;
• The second is intended mainly for staff of administrative divisions; it serves the Email of all other NSU domains (nsu.ru, post.nsu.ru, etc.) and is based on Zimbra.

Respectively,

• If your email address after the @ symbol indicates g.nsu.ru, alumni.nsu.ru or non-employee.nsu.ru, then the information for you is located here
• If your email address after the @ symbol indicates something else like *.nsu.ru, then the information for you is located here
