At the moment i am using another pannel but but i am thinking of switching to ispconfig permanently. Just some things are not clear to me and i dont seem to find it. Is there letsencrypt integrated into the pannel or do i have to add it myself is there a addon for the letsencrypt so maybe somebody can give me some advise and point me in the right direction
Use on of the perfect-setup-guides an LE is installed on your server. You can enable LE for every website.
Yeah you dont have to use addons, its all integrated in the latest ISPC. Just check the LE box and if everything is setup correct (DNS, WEB) it will get you your SSL cert automaticly.
Follow this guide https://www.howtoforge.com/tutorial/perfect-server-debian-jessie-nginx-bind-dovecot-ispconfig-3.1/ And it should work fine or if you want apache https://www.howtoforge.com/tutorial...8-4-jessie-apache-bind-dovecot-ispconfig-3-1/
