OCSP Must Staple - Let's Encrypt - ending our support for that feature

[TravisWilder]

Summary

Hi - just got an email and I did not found any changes / pulls lately on this:

The certificates for the hostnames below (issued by the Let's Encrypt account associated with this email address) use a feature called "OCSP Must Staple." We are ending our support for that feature (https://letsencrypt.org/2024/12/05/ending-ocsp), along with our support for OCSP in general, and replacing it with Certificate Revocation Lists (https://letsencrypt.org/2022/09/07/new-life-for-crls).

After May 7th, 2025, requests for certificates with "OCSP Must Staple" will fail.

To ensure your certificates continue to automatically renew, please change your ACME client configuration to not request OCSP Must Staple.

Motivation

Let's Encrypt will continue to work as the mail list all my MailCow Domains I assume the setting is set to "must staple"

Additional context

mailcow doesn’t use OCSP Must-Staple, so no action is needed.

you are totally right - I need to excuse myself for opening the ticket.
Domains affected are NOT mailcow related - sorry
