Control: tags -1 + moreinfo Hi Yanko,
thanks for your report! Please help me to understand what's happening by providing the following information: * How exactly is arpwatch invoked? Please provide the output of `ps -U arpwatch -F` or (in case that doesn't show any processes) `ps -eF | grep arpwatch`. * The output of `dpkg -S /usr/lib/sendmail` so I know which Debian package is providing the /usr/lib/sendmail binary installed in your system. Thanks Lukas
