piperino it works as intended 🙂
That’s my setting:
ADDITIONAL_SAN=mail.*,sogo.*
So all my configured domains in mailcow get two additional SANs (mail.example.com and sogo.example.com) in the main certificate
Ah, I think now I understand what you meant 😃 no, it’s not the mail* wildcard ACME uses, the asterisk is just a placeholder for all domains you configured in the mailcow UI. So the final SAN will be mail.domain1.tld, mail.domain2.tld and so on
