Recently, & without notice, all local addresses of the form
@blah.cc.columbia.edu have simply become @columbia.edu as a
mailhub server has come online.  Thus, [log in to unmask]
now sends and receives mail as [log in to unmask]  The administrative
VM machine hosts many local lists and I'm wondering what options,
if any, are available for modifying the addresses of affected
subscribers beside the brute editing of each list.
 
Thanks in advance,
