[sudo-sys] Let's Encrypt Expiration Emails Update

Hi, As a Let’s Encrypt Subscriber, you benefit from access to free, automated TLS certificates. One way we have supported Subscribers is by sending expiration notification emails when it’s time to renew a certificate. We’re writing to inform you that we intend to discontinue sending expiration notification emails. You can learn more in this blog post: https://letsencrypt.org/2025/01/22/Ending-Expiration-Emails Here are some actions you can take today: Automate with an ACME Client that supports Automated Renewal Information (ARI). ARI enables us to automatically renew your certificates ahead of schedule should the need arise: https://letsencrypt.org/2024/04/25/guide-to-integrating-ari-into-existing-a… Sign up for a third-party monitoring service that may provide expiration emails. We can recommend Red Sift Certificates Lite, which provides free expiration emails for up to 250 active certificates: https://redsift.com/pulse-platform/certificates-lite Opt in to emails. While we are deprecating expiration notification emails, you can opt in to continue to receive other emails.
