[Zabbix-users] Zabbix 5.4 email alerts and SMTP configuration

[Jeff C. <sc...@un...>]

"We use Zabbix 5.4 inside a VPN.  We have our own Postfix email server
inside that VPN that forwards email to a campus email server outside
the VPN.  To do aliasing we've set up a bogus domain recognized by our
Postfix server different from the proper domain in the SMTP helo field
in Zabbix.  Sending email to alert@[bogus_domain] gets resolved and works
from the CLI.  Sending email based on an event from Zabbix, gets rejected
by the campus email server because the SMTP helo domain and bogus_domain do
not match.  Has anyone tried something similar and had it work?"
