Dear everyone,

i am using Letsencrypt via acme-client to obtain certs for my server. My questions are,

1) How could i make all services Postfix, Dovecot, Openldap, Nginx can use multi certs which are provided by Letsencrypt?

2) Is that possible to combine all certs into one after obtaining from Letsencrypt?

3) Does Letsencrypt support multi domains, like SAN?

Thank you.
