letsencrypt.sh request `hostname`

With Let's Encrypt you can generate a free SSL certificate for your whole server: SMTP, POP3, IMAP, FTP, the webserver(s) and DirectAdmin is covered by this. First, you need to have Let's Encrypt enabled. Secondly, this only works for the server hostname.

Navigate to the directory:
cd /usr/local/directadmin/scripts
Request the certificate:
sh letsencrypt request serveame.yourwebhoster.eu
Make sure that the following services are restarted, if installed:
apache
exim
dovecot
proftpd
pureftpd
nginx
DirectAdmin will take care of regenerating the Let's Encrypt certificate
