Dear Martin, 

1. Check if test email is sended
2. Make sure that you click checkbox "send email" or create user screen
3. Make sure that sended emails are not go to spam by your email server

[Martin Fidel]

Check all of that already :) not the first time I use jira.

Usually we have troubles with e-mail server settings. 

Try to contact your email server admin and check for sended letters.

Also try to check mail queue: https://confluence.atlassian.com/doc/the-mail-queue-151387.html

There is no problem with the email server, I receive the email for my user, just new users dont receive it
