Routing mail through a heterogenous internet presents many new
|
|
problems. Among the worst of these is that of address mapping.
|
|
Historically, this has been handled on an ad hoc basis. However,
|
|
this approach has become unmanageable as internets grow.
|
|
|
|
Sendmail acts a unified "post office" to which all mail can be
|
|
submitted. Address interpretation is controlled by a production
|
|
system, which can parse both old and new format addresses. The
|
|
new format is "domain-based", a flexible technique that can
|
|
handle many common situations. Sendmail is not intended to perform
|
|
user interface functions.
|
|
|
|
Sendmail will replace delivermail in the Berkeley 4.2 distribution.
|
|
Several major hosts are now or will soon be running sendmail.
|
|
This change will affect any users that route mail through a sendmail
|
|
gateway. The changes that will be user visible will be discussed.
