In previous versions of Zabbix, the exit code of a Zabbix sender worked correctly. However, starting from version 7.0.X there is an issue: even if the Zabbix sender fails, the exit code returns 0 when it should return 2. Test added in comments.

Steps to reproduce:

1. Using Zabbix sender on non existent host 

Result:
Exit status: 0
Expected:
Exit status: 2
