I renamed some install scripts to be more clear. SPF: Suggest [MAILDOMAIN], [HOSTNAME] and [IP ADDRESS] Its a better practice to be more inclusive when it comes to dns SPF records. DKIM: Some dns registrars truncate dns TXT records at 255 chars. So 2048bit do not fit (about 390 vs. 230 chars). So 1024bit keys are a good choice, after all it is only a mail verification mechanism, do not encrypt the mail... Show tip how to stop systemd service (03_install_check_running_services.sh) sudo su prefered to become root, sudo su fails with npm permission errors when installing (dunno why). A mini tutorial is shown at the end about SPF, DKIM and how to add/remove/modify DKIM keys. This pull request closes issue 85,86.
