+.Nm Mail.local
+reads the standard input up to an end-of-file and appends it to each
+.Ar user's

+file.

+.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 
+.Xr flock 2
+while mail is appended,
+and a
+.Pa user.lock
+file also is created while the mailbox is locked
+for compatibility with older MUAs.
+.Pp
+If the ``biff'' service is returned by
+.Xr getservbyname 3 ,
+the biff server is notified of delivered mail.
