we use letsencrypt since 2018 for our mail server but this time,
we can't renew our certificat and get this message :

how to resolve this problem?



Hello @bendida , welcome to the Let's Encrypt community. :slightly_smiling_face:
Given the information you have supplied so far I suggest look at Email feedback: TLS 1.0/1.1 deprecation and SHA-1 deprecation
Also take a look at Documentation - Let's Encrypt for the Rate Limits - Let's Encrypt

Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help. Domain names for issued certificates are all made public in Certificate Transparency logs (e.g. |, so withholding your domain name here does not increase secrecy, but only makes it harder for us to provide help.

My domain is:

I ran this command:

It produced this output:

My web server is (include version):

The operating system my web server runs on is (include version):

My hosting provider, if applicable, is:

I can login to a root shell on my machine (yes or no, or I don't know):

I'm using a control panel to manage my site (no, or provide the name and version of the control panel):

The version of my client is (e.g. output of certbot --version or certbot-auto --version if you're using Certbot):

Thank you for assisting us in helping YOU!


Please use one of the 5 (!) certificates you've had issued within the last 168 hours.


the requests fail to create any valide certificat.

That is not correct @bendida. You have been issued certs. It is most likely your mail server is just not using them. The error message links to the page below which explains more.

If you complete the form shown by bruce5051 as best you can we can give better advice.
