Dovecot cert backup

SYSTEM INFORMATION
Debian Linux 10 REQUIRED
7.1-1 REQUIRED

Hello all,

while renewing a website SSL certificate, I accidently clicked on Apply to all services (Dovecot, Postfix, etc…). That was a real mistake because the original mail server certificate was an auto-signed one and thus got replaced by the freshly renewed website one. Any clue where to find in the daily backup the original /etc/private/*.key or dovecot.key ?

You should be able apply all to the original to take you back,
