NAME
       mail.local - store mail in a mailbox

SYNOPSIS
       /usr/lib/mail.local [-f sender] [-d] recipient

DESCRIPTION
       mail.local  reads the standard input up to an end-of-file and appends it to each user's mail file (mailbox). This program is intended to be
       used by sendmail(1M) as a mail delivery agent for local mail. It is not a user interface agent.

       Messages are appended to the user's mail file in the /var/mail directory. The user must be a valid user name.

       Each delivered mail message in the mailbox is preceded by a "Unix From line" with the following format:

       From sender_address time_stamp

       The sender_address is extracted from the SMTP envelope address (the envelope address is specified with the -f option).

       A trailing blank line is also added to the end of each message.

       The mail files are locked with a .lock file while mail is appended.

       The mail files are created with mode 660, owner is set to recipient, and group is set to mail. If the ``biff'' service is returned by  get-
       servbyname(3SOCKET),  the  biff	server	is notified of delivered mail. This program also computes the Content-Length: header which will be
       used by the mailbox reader to mark the message boundary.

OPTIONS
       The following options are supported:

       -f sender    Specifies the "envelope from address" of the message. This flag is technically optional,  but should be used.

       -d	    Specifies the recipient of the message. This flag is also optional and is supported here for backward compatibility. That  is,
		    mail.local recipient is the same as mail.local -d recipient.

       -l	    Turn on LMTP mode.

       -r from	    Specify the sender's name (for backward compatibility).

       -7	    Do not advertise 8BITMIME support in LMTP mode.

       -b	    Return a permanent error instead of a temporary error if a mailbox exceeds quota.

OPERANDS
       The following operand is supported:

       recipient    The recipient of the mail message.

ENVIRONMENT VARIABLES
       TZ    Used to set the appropriate time zone on the timestamp.

EXIT STATUS
       The following exit values are returned:

       0     Successful operation.

       >0    An error occurred.
