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 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: –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.
