 If @code{lyskomd} has been down for X minutes, where @code{Mail after
 downtime} <= X < @code{Mail until downtime}, @code{updateLysKOM} will
 send a mail message to the mail address found on the first line of the
 status file.  Actually, it is the age of the status file (named with
 @code{Status file}) that is measured.
+The defaults are 60 and 120, respectively.
+
+@item sendmail path: @var{path}
+Path to the @code{sendmail}-compatible program that
+@code{updateLysKOM} should use to send mail.  This program will be
+invoked with a @samp{-t} option via a @samp{popen()} call.  It should
+accept an email header, a blank line, an email body, and a terminating
+line consisting of a single @samp{.} on standard input.
+The default is found at configure time.  The special value @samp{:}
+means that no mail will ever be sent.
