Is this box a Windows system or *nix? In windows, PHP acts differently and
uses a different set of php.ini settings to do email stuff. Of importance
is a setting which sets the sender. If you haven't specified a fully
qualified email address for the sender, this is why. Use php@??? or
something as a default (not @localhost as remote systems typically reject
that), and then tell your clients they must use ini_set() to override the
default.
If it's not a Windows box, try the same thing anyways just to see. I don't
know which variable the one you want to set is off the top of my head, but
look in the php.ini file for "sendmail" and you should find it.
