Hi there,
I'm trying to install a chatmail server at xat.and4po.cat and when trying to setup the CAA record on the DNS administrator from my registrar (DonDominio) i run into a problem. Following the installation help tool from the chatmail server I need to add the following DNS record xat.and4po.cat. CAA 0 issue "letsencrypt.org;accounturi=https://acme-v02.api.letsencrypt.org/acme/acct/<some_numbers>" (hid the numbers just in case). However, when I try to add the content from the DNS administrator it gets auomatically changed to xat.and4po.cat. 60      IN      CAA     0 issue "acme-v02.api.letsencrypt.org".
I know that other people were able to setup the record without major problems with other DNS managers. So I asked the service support and they told me to ask you if there's an alternative link I can use to do the certification.
Thank you,
