Thanks for your replies. I tried systemctl stop fetchmail.service
I tried 4 times. then I tried /etc/init.d/fetchmail stop but although dead for 6 hours, fetchmail continued to fetch mails. So I tried root@titan ~ ps -ef | grep fetch fetchma+ 1264 1 0 Sep25 ? 00:06:33 /usr/bin/fetchmail -f /etc/fetchmailrc --pidfile /var/run/fetchmail/fetchmail.pid --syslog root@titan ~ kill 1264And the fetchma+ process disappeared - I hope it no longer rises from the dead.
