the default sendmail configuration assumes that a machine that is
generating outbound smtp messages is properly configured to receive
them at the same name. if your host calls itself one thing, but is
known in the dns as something else, or if you wish to use a third name
for some reason, that's not "standard", and you can't expect not to
have to do at least a little reconfiguration.
