But your second suggestion, to take the trouble plough- ing through "man 5 sudoers" helped: under the zillions of options for the "Defaults" instruction I eventually found option "mailto" which ei- ther takes a mail address as argument or can be prefixed with "!" in or- der to prevent mailing altogether. So I just created a new file in directory "/etc/sudoers.d/" containing the line Defaults !mailto Sincerely, Rainer
