Thank you very much for the information.
Another question,
If we need to receive all email with Zimbra using @ABC.com domain, then forward/relay those emails to the other multiple mail servers within our organizations.
Is there a way to setup with Zimbra?
The request from my boss now is,
1. Receive all email with Zimbra using
xxx@ABC.com
2. Forward/Relay mails to other mail server (depends on user)
user a,b,c forward mail to server: 10.10.10.10
user d,e,f forward mail to server: 20.20.20.20 etc
If we do this one by one, it take long time. So is there way to create the group and put users in the group,then set up forward/relay by this group?
Thank very much in advance.
