Routing Mail Between Exchange 2010 Internal and GoDaddy POP3 External During Migration For A Single Domain
Posted on 2011-03-18
We have a newer client that is currently using hosted POP3 email with GoDaddy. We will be migrating them off of GoDaddy to an internal Exchange 2010 server. A lot of our clients are on McAfee Email Protection (formerly MXLogic) and we have used the intelligent routing option frequently when migrating email. We do have McAfee Email Protection in place for this customer but had to remove it because of issues with GoDaddy. (Will say from experience and the number of clients/mailboxes that uses McAfee/MXLogic that we have never had these issues EXCEPT with GoDaddy). Now we could use the intelligent routing component and the migration would be easy. However, they have specified that they do not want any issues during the migration with GoDaddy even though they concede the issues were with GoDaddy.
I am thinking the best way to do this is set up forwarding from GoDaddy for individual mailboxes as they are migrated over to Exchange 2010. Have researched how GoDaddy handles that and it looks like we will have to add a forwarding package for them.
When we forward from GoDaddy I believe I need to set up an alias or sub-domain to point to the Exchange 2010 server?
What needs to happen on the Exchange 2010 server so users who are on Exchange 2010 can send email to the users still on GoDaddy?
