The first part, "domains = " , is a domain list so it can contain eg
"rubbish.com:nonsense.com" or a file name. See "Domain lists" in the
on-line documentation.
The second part, "new_address = " , is an expanded string. See
"String expansions" in the on-line documentation but yes, the
expansion can contain a database look-up.
