Problem with certificate


Please fill out the fields below so we can help you better. Note: you must provide your domain name to get help.

Hi @techcomputerworld

you have 5 identical certificates created (Google lists 5 pre and 5 leaf certificates):;include_subdomains:false;

So you hit the limit.

Why don’t you use one of these?


Hi, thanks for your response, I have deleted the certificates with order rm -rf directory, I’ve used certbot delete --cert-name and, but the certiicate, don’t run, I want to use the mail server postfix and dovecot and the certificate does not work for me it gives me the error that and it does not let me create it, delete by error.


Then you have to wait one week.

Never, never, never delete active and valide certificates.


the certificate don’t run, I’ve created the certificate.
certbot-auto certonly -d
the certificate I can ask the people of let’s encrypt to invalidate the certificate that I deleted it by mistake


This doesn’t change something. Please read

Revoking certificates does not reset rate limits, because the resources used to issue those certificates have already been consumed.


Is it posible use let’s encrypt certificates, for mail server?


Yes, it’s possible. You have three:;include_subdomains:false;
