.SH DESCRIPTION
.I Send
is not normally run directly by the user.  Instead, mail protocol
agents like
.I smtpd
(see
.IR smtp (8))
and mail preparers like
.IR marshal (1)
fork and execute
.IR send .
.PP
.I Send
reads a message from standard input and disposes of it in one
of four ways:
.IP \(bu 3
If
.I mailaddr
refers to a local mailbox, it appends it to the
recipient's mailbox.
.IP \(bu
If
.I mailaddr
is remote, it queues the mail for remote delivery.
.IP \(bu
If the
.B -r
option is given and the mail is undeliverable, it
returns the mail to the sender.
.IP \(bu
if the
.B -r
option is not given and the mail is undeliverable, it
appends the mail to
.BI /mail/box/ username /dead.letter
and prints a message to standard error.
.PP
The file
.B /mail/lib/rewrite
determines exactly how to deliver or queue the mail.
The decision is based purely on the recipient address.
.PP
The options are:
.TF -b
.TP
.B -b
suppresses the addition of the
.B To:
line.
.TP
.B -i
let the message input be terminated by a line
containing only a period, for
compatibility with
old mailers.
.TP
.B -x
do not send mail, but instead report
the full mail address of the recipient.
.TP
.B -#
do not send mail, but instead report
what command would be used to send the mail.
.TP
.B -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 -b
option.
.PD
.PP
.I Send
uses the login name as the reply address.
