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 preparers like marshal(1) fork
and execute send.
Send reads a message from standard input and disposes of it in one of
four ways:
• If mailaddr refers to a local mailbox, it appends it to the recipi‐
ent's mailbox.
• If mailaddr is remote, it queues the mail for remote delivery.
• If the -r option is given and the mail is undeliverable, it returns
the mail to the sender.
• if the -r option is not given and the mail is undeliverable, it ap‐
pends the mail to /mail/box/username/dead.letter and prints a mes‐
sage 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.
