We have hundreds of domain hosted on Zimbra server. Suppose I want to shift domain1.com from the server to other server. I update MX records.
There also domain2.com hosted on Zimbra server. If any users from domain2.com sends mail to domain1.com it delivers locally. I want to deliver it to the server which serves as MX for the domain instead of delivering locally.
This means I want to keep the domain on the server but want to disable the local delivery for the that domain.
