.SH DESCRIPTION
.B Mail.local
reads the standard input up to an end-of-file and appends it to each
.I user's
.B mail 
file.  The
.I user
must be a valid user name.
.PP
The options are as follows:
.TP 1i
.B \-7
Do not advertise 8BITMIME support in LMTP mode.
.TP 
.B \-b
Return a permanent error instead of a temporary error
if a mailbox exceeds quota.
.TP 
.B \-d
Specify this is a delivery (for backward compatibility).
This option has no effect.
.TP 
.BI \-D " mbdb"
Specify the name of the mailbox database
which is used to look up local recipient names.
This option defaults to "pw", which means use getpwnam().
.TP 
.BI \-f " from"
Specify the sender's name.
.TP
.B \-l
Turn on LMTP mode.
.TP 
.BI \-r " from"
Specify the sender's name (for backward compatibility).
Same as \-f.
.TP
.BI \-h " filename"
Store incoming mail in \fIfilename\fR in the user's home directory instead
of a system mail spool directory.
.PP
Individual mail messages in the mailbox are delimited by an empty
line followed by a line beginning with the string ``From ''.
A line containing the string ``From '', the sender's name and a time stamp
is prepended to each delivered mail message.
A blank line is appended to each message.
A greater-than character (``>'') is prepended to any line in the message
which could be mistaken for a ``From '' delimiter line
(that is,
a line beginning with the five characters
``From '' following a blank line).
.PP
The mail files are exclusively locked with 
flock(2) 
while mail is appended, 
and a
.B user.lock
file also is created while the mailbox is locked 
for compatibility with older MUAs.
.PP
If the ``biff'' service is returned by 
getservbyname(3), 
the biff server is notified of delivered mail.
.PP
The
.B mail.local
utility exits 0 on success, and >0 if an error occurs.
.SH ENVIRONMENT
.IP TZ
Used to set the appropriate time zone on the timestamp.
.SH FILES
.PD 0.2v

sendmail.cf file.

(handling mailbox reading as well as mail delivery)
appeared in 
Version 7 AT&T UNIX
