zabbix-server: Only allow local SMTP relay

Browse Source 
The Zabbix server also serves an SMTP relay, to minimize reliance on
external services when sending notifications. Since it inherits
configuration of the relay from the general *smtp-relay* group, it ends
up allowing all hosts to relay off of it. To avoid this, we set
`smtp_rmynetworks` at the *zabbix-server* group level to only allow the
local machine to relay messages.
