I am in the mid of migrating one of our sister company to HQ thus I had created another domain in SmarterMail. However, it will take me some time in order to complete the whole migration, during the time of migration, HQ user will have email bounced back every time they try to reach our sister company.

 

So, the question is - how to I disable local delivery in smartermail so that I can complete the migration process without issue ?
