I have a multiserver and multidomain zimbra installed. I'm having some problems with the HELO identification when I send some mails on remote servers.
I've check the SmtpHostname (zmprov gacf|grep SmtpHostname) and I get 3 hostname. The first one is Localhost and the other two are the public name of the domains in zimbra, so I assume its correct.
But still I have some mails rejected because I'm sending the local name to the remote server.
Any Idea? Something to check?
