XADM: SMTP Proxies are Set to "@site.org.com" by Default

SUMMARY

When you use the Microsoft Move Server Wizard the wizard will, by default, generate new SMTP proxies which have a "@site.org.com" format. All the recipients of SMTP addresses are then modified to this format. The newly generated proxy addresses are set as reply address. This may not be the expected result if the server is moved within the same organization.

Changing the site addressing object to what it was before the move (for example, "@org.com"), will not set the proxy addresses as Reply address because the proxy already exists.
