Question on certificates


I received this email below. I would like to know what this is for exactly as I wasn’t briefed by the web designers/hosts about this.


Your certificate (or certificates) for the names listed below will expire in 19 days (on 20 Feb 19 04:42 +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 for details.

For any questions or support, please visit Unfortunately, we can’t provide support by email.

Don’t worry about this email.

It looks like your developers/designers removed the “webmail.” subdomain from your SSL certificate, which leads to this somewhat misleading email being sent to you. You can find more information about this phenomenon here:

Because the certificate was subsequently replaced, you do not need to take any action.


OK great. Thanks a lot.
