[Admin] Let's Encrypt certificate expiration notice for domain "mail.ffnw.de"

Hello,

Your certificate (or certificates) for the names listed below will expire in 20 days (on 10 Oct 18 09:49 +0000). Please make sure to renew your certificate before then, or visitors to your website will encounter errors.

We recommend renewing certificates automatically when they have a third of their
total lifetime left. For Let's Encrypt's current 90-day certificates, that means
renewing 30 days before expiration. See
https://letsencrypt.org/docs/integration-guide/ for details.
