send - mail routing and delivery

upas/send [ -b ] [ -i ] [ -r ] [ -x ] [ -# ] [ mailaddr ... ]

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 recipient'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 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: .TF -b

-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.
