mail.local(1M)

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  mes-
     sage.

     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 getservbyname(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 com-
           patibility. 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  compatibil-
           ity).

     -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.
