TLS certificate error with mail host aliases

Support

Hi @davidep

It’s easy to find the certificate-mail.domain.com.yml. Per the docs, I believe the correct syntax would be this:

http:
  routers:
    certificate-mail.domain.com:
      entrypoints: https
      service: ping@internal
      rule: Host(`mail.domain.com`) && Path(`/cd98a9c8-24c2-441b-a6d5-159afe0b1822`)
      priority: '1'
      tls:
        domains:
        - main: mail.domain.com
          sans:
            - "smtp.domain.com"
            - "imap.domain.com"
        certresolver: acmeServer

However, I don’t see any way to check my work. :slight_smile: I don’t get any indication the certificate refreshes and so far at least my mail client continues to complain of a bad cert. Is there a way to view the generated cert? Or to “refresh” traefik?
