The default .Nm mail command is described in .Xr Mail 1 . .Pp .Nm Mail with no argument prints a user's mail, message-by-message, in last-in, first-out order; the optional argument .Ic + displays the mail messages in first-in, first-out order. For each message, it reads a line from the standard input to direct disposition of the message. .Tw Fl .Tp Li newline Go on to next message. .Tp Ic d Delete message and go on to the next. .Tp Ic p Print message again. .Tp Fl Go back to previous message. .Tc Ic s .Op Ar file .Cx \&... .Cx Save the message in the named .Ar files (`mbox' default). .Tc Ic w .Op Ar file .Cx \&... .Cx Save the message, without a header, in the named .Ar files , .Pa mbox is the default. .Tc Ic m .Op Ar person .Cx \&... .Cx Mail the message to the named .Ar persons (yourself is default). .Tp Li EOT (control-D) Put unexamined mail back in the mailbox and stop. .Tp Ic q Same as .Li EOT . .Tc Ic \&! .Ar command .Cx Escape to the Shell to do .Ar command . .Tp Ic \&* Print a command summary. .Tp .Pp An interrupt normally terminates the .Ar mail command; the mail file is unchanged. The optional argument .Fl i tells .Ar mail to continue after interrupts. .Pp When .Ar persons are named, .Ar mail takes the standard input up to an end-of-file (or a line with just `.') and adds it to each .Sf Ar person \'s .Pa mail file. The message is preceded by the sender's name and a postmark. Lines that look like postmarks are prepended with `>'. A .Ar person is usually a user name recognized by .Xr login 1 . To denote a recipient on a remote system, prefix .Ar person by the system name and exclamation mark (see .Xr uucp 1 ) . .Pp The .Fl f option causes the named file, for example, .Pa mbox , to be printed as if it were the mail file. .Pp When a user logs in he is informed of the presence of mail. .Sh ENVIRONMENT .Tw Fl .Tp Ev HOME The .Ev HOME variable is used by .Nm delivermail to find the file .Pa mbox. .Tp Ev HOSTALIASES Used to find host aliases. .Tp Ev NAME .Nm Delivermail extracts the users full name from the .Ev NAME variable. .Tp Ev TZ Used to set the appropriate time zone on the postmark. .Sh FILES .Dw /var/spool/mail/* .Di L .Dp Pa /etc/passwd to identify sender and locate persons .Dp Pa /var/spool/mail/* incoming mail for user * .Dp Pa mbox saved mail .Dp Pa /tmp/ma* temp file .Dp Pa dead.letter unmailable text .Dp .Sh SEE ALSO .Xr Mail 1 , .Xr write 1 , .Xr uucp 1 , .Xr uux 1 , .Xr xsend 1 , .Xr sendmail 8 .Sh HISTORY .Nm Delivermail appeared in Version 7 AT&T Unix as the program .Nm mail. .Sh BUGS Race conditions sometimes result in a failure to remove a lock file. .Pp Normally anybody can read your mail, unless it is sent by .Xr xsend 1 . An installation can overcome this by making .Nm mail a set-user-id command that owns the mail directory.
