We have a domain setup on a Zimbra server and when an employee sets up the auto-reply it works just fine if sent to that address. I was asked to create aliases to all of those addresses from our primary mail system.
So the domain, for example on Zimbra is ispteam.com but isp.com aliases on another mailsystem were created for each ispteam. Naturally the autoreply works just fine if mail is sent directly to ispteam.com but not to isp.com which forwards directly to the Zimbra address.
Is there a way around this that anyones aware of on Zimbra?
