.Sh NAME
.Nm mail.local
.Nd store mail in a mailbox
.Sh SYNOPSIS
.Nm
.Op Fl l
.Op Fl f Ar from
.Ar user ...
.Sh DESCRIPTION
.Nm
reads the standard input up to an end-of-file and appends it to each
.Ar user's
.Pa mail
file.
The
.Ar user
must be a valid user name.
.Pp
The options are as follows:
.Bl -tag -width xxxxxxx
.It Fl f Ar from
Specify the sender's name.
.It Fl l
Request that
.Nm username.lock
files be used for locking.
.El
.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 (``\*[Gt]'') is prepended to any line in the message
which could be mistaken for a ``From '' delimiter line.
.Pp
If the
.Op Fl l
flag is specified mailbox locking is done with
.Nm username.lock
files.
Otherwise, the mailbox is exclusively locked with
.Xr flock 2
while mail is appended.
.Pp
If the ``biff'' service is returned by
.Xr getservbyname 3 ,
the biff server is notified of delivered mail.
.Pp
The
.Nm
utility exits 0 on success, and \*[Gt]0 if an error occurs.
.Sh ENVIRONMENT

.It Ev TZ
Used to set the appropriate time zone on the timestamp.
