NethServer Version: 7.3
Module: lets encrypt
Im using NS7 as my homeserver for web, mail and some other cool stuff. For encryption of course letsencrypt is being used.
By default, a certificate has a validity of 3 months, and after that, it’s automatically renewed. Great feature! But after a renewal, my whole family has to accept the new certificate, both for sending and receiving mail on smartphone, ipad, laptop, etc. That’s a bit often for the use I make of it.
Is it possible to extend the lifetime of a cert to 6 months, or even a year?
I’ve found the .conf file in /etc/letsencrypt/renewal but that doesn’t say anything on validity.
