Sendmail acts as a unified "post office" to which all mail can be
|
|
|
|
|
submitted. Address interpretation is controlled by a production
|
|
|
|
|
system, which can parse both domain-based addressing and old-style
|
|
|
|
|
"ad hoc" addresses. The production system is powerful enough to
|
|
|
|
|
rewrite addresses in the message header to conform to the standards
|
|
|
|
|
of a number of common target networks, including old (NCP/RFC733)
|
|
|
|
|
Arpanet, new (TCP/RFC822) Arpanet, UUCP, and Phonenet. Sendmail
|
|
|
|
|
also implements an SMTP server, message queueing, and aliasing.
