move default domain mailboxes

[Stephen Ingram]

After setting up murder, is it possible to move mailboxes that use the
default domain from one backend server to another? The new back-end
server has a different default domain. After which the default domain
on the original backend server will be changed.

before:

server 1 default domain: domainA.tld

mailbox for user steve at domainA.tld is user.steve

server 2 default domain: domainB.tld


next:

server 1 default domain: domainA.tld

move mailbox for user steve at domainA.tld to server 2

server 2 default domain: domainB.tld

mailbox becomes user.steve at domainA.tld


finally:

server 1 default domain: domainC.tld

server 2 default domain: domainB.tld

mailbox user steve at domainA.tld is still user.steve at domainA.tld
