Hi, Thanks for your bug report.
> After upgrading davmail, it did not start. /usr/bin/davmail is now a jar > file; it doesn't run without java. /usr/bin/davmail is a jar file that gets executable using jarwrapper. > /etc/init.d/davmail start > dows not give any information. (and does not start the server). Please provide the output of the lat lines of: $ sudo bash -ex /etc/init.d/davmail start It should end with: start-stop-daemon: user '_davmail' not found + return 2 This is normal as the _davmail user only gets created if you're not using systemd. If you're using systemd, the _davmail user is created dynamically by systemd, but you should use systemd to start davmail: $ sudo systemctl start davmail You can check that davmail is running using: $ systemctl status davmail You can enable davmail on boot using: $ systemctl enable davmail Thanks, Alex
