NAME
send - mail routing and delivery
SYNOPSIS
upas/send [ -b ] [ -i ] [ -r ] [ -x ] [ -# ] [ mailaddr ...
]
DESCRIPTION
Send is not normally run directly by the user. Instead,
mail protocol agents like smtpd (see smtp(8)) and mail pre-
parers like marshal(1) fork and execute send.
Send reads a message from standard input and disposes of it
in one of four ways:
+o If mailaddr refers to a local mailbox, it appends it to
the recipient's mailbox.
+o If mailaddr is remote, it queues the mail for remote
delivery.
+o If the -r option is given and the mail is undeliverable,
it returns the mail to the sender.
+o if the -r option is not given and the mail is undeliver-
able, it appends the mail to
/mail/box/username/dead.letter and prints a message to
standard error.
The file /mail/lib/rewrite determines exactly how to deliver
or queue the mail. The decision is based purely on the
recipient address.
The options are:
-b suppresses the addition of the To: line.
-i let the message input be terminated by a line containing
only a period, for compatibility with old mailers.
-x do not send mail, but instead report the full mail
address of the recipient.
-# do not send mail, but instead report what command would
be used to send the mail.
-r input is via a pipe from another program. Expect a From
line at the start of the message to provide the name of
the sender and timestamp. This implies the -b option.
Send uses the login name as the reply address.
