Good Morning,

i have zimbra zcs open source version. Some users have many pop3 external downloader with many different mail and domains..

Is there any solution for send email with different smtp if i send email received with my pop3 external account?

Is it possible send all outbound email to external smtp server ?

I've read that i can do it with relay_host in /etc/postfix/main.cf but nothing happen after that change.

Thank'you at all...
