# If you wish to delegate the DNS challenges to another domain, you can set the suffix variable. For example:
# suffix=".dns-01.example.org"
# And then add the appropriate CNAME records to delegate the challenges:
# _acme-challenge.www.example.com CNAME _acme-challenge.www.example.com.dns-01.example.org
# _acme-challenge.www.example.net CNAME _acme-challenge.www.example.net.dns-01.example.org
# In this case, the zone ID must refer to the delegated domain, and the API token must have edit
# permissions (only) for that domain.
