SENDMAIL(1)SENDMAIL(1)NAME
sendmail - send mail messages
SYNOPSIS
sendmail [ recipient ... ]
DESCRIPTION
Sendmail sends mail to each recipient named as an argument. It reads
its standard input to get the text of the message. If no recipient is
named, the recipient(s) will be taken from the message header.
The mail message is scanned for lines beginning and
If no `from' line is found, the sender is assumed to be the current
user. The recipient(s) of the message can be mentioned as arguments or
in a list of names in a line but not as both. If the sender's name is
unqualified (is just a user name), sendmail appends the value of the
environment variable
Sendmail delivers the mail using the module smtp(2), which connects to
a mail server running the Simple Mail Transport Protocol (SMTP), using
the symbolic host name $MAILSERVER (see db(6)).
