.Sh DESCRIPTION
.Nm Mail.local
reads the standard input up to an end-of-file and appends it to each

call that forces the mailbox to be committed to disk before returning a
.Dq success
status.
.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 (``>'') is prepended to any line in the message
which could be mistaken for a ``From '' delimiter line.
.Pp
The mail files are 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.

utility exits 0 on success, and >0 if an error occurs.
