I have read this https://letsencrypt.org/docs/expiration-emails/ to get clarification of the process involved, but does not answer my problem - as i read this form it “If your certificate is already renewed, we won’t send an expiry notice.”
We have renewed our Exchange certificate and still getting expiration noticed even though its not due until April '18
Please advise on this, clicking on unsubscribe might solve problem for now, but I dont want to fall in situation that my cert renewal notice is missed and if auto-renewal fails we have a problem.
I can share my ch.sh on the affected SAN domains involved in PM.
The system sends warnings if the exact same certificate has not been renewed. If you removed a SAN then it will send you the email warnings because that certificate ( including the SAN) has not been renewed.
SO if i understand this correctly… the old SAN cert, LE mailing-list still consider this valid only in an expiration sense when it comes to emails notifications.
In actual fact, the new SAN cert we will begin to receive noticed 20+days before expiring, but for the old SAN cert we continue until we manually stop notifications.
