Renaming Default Domain

Has anyone changed the default domain (first vdomain + at
least 4 other
places?). We need to do this,
And AFAIKS it just needs swapping the contents of the first
vdomain with
the new default, plus changing the
Domain name in g_received_name in SurgeMail.ini, all places
in
dlist.ini, at the top of sendmail.ini, and 3
Places in webmail.ini.

Anyone already done this with success?
