Yes, the restore function uses the same code as normal alias creation,
both of which run 'newaliases'. At least, they do in the most recent
version of Virtualmin (2.610).

Perhaps I could login to your server myself to see what is happening?

Are you just moving Virtualmin domains with the backup/restore function?
If so, this should work fine.
