I had successfully installed getssl certificates on my old server. When I transfered some domains to a new server, I removed them from the SANS= line in getssl.cfg. Still I get expire messages via email for these domains, even when they are working fine on the new server, and can verify they are not expired there. I never revoked these domains.
which expires in Feb. Since the domains are different, Let's Encrypt considers this a different certificate, hence will still send you emails about the old cert.
Some of the certificate you issued in November aren’t an exact match to your latest certificate, for example this one: https://crt.sh/?id=52470536
You will receive expiration notices for each certificate like that unless the renewed certificate includes the exact same set of domains (no additions, no removals).
Your options are to either unsubscribe from all expiration notices through the link in the notice (and monitor the expiration on your end) or continue to ignore the messages. There’s currently no way to unsubscribe only from expiration notices for specific certificates.
