.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
|
2017-03-12 16:36:04 +00:00
|
|
|
option is given and the mail is undeliverable,
|
|
|
|
|
the message
|
|
|
|
|
.B "mail rejected:"
|
|
|
|
|
is printed on standard error, setting exit status.
|
2011-03-30 13:49:47 +00:00
|
|
|
.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.
