Problem with renewed SSL certificate and Email

CWP 0.9.8.1210 on AlmaLinux 9.6

So when CWP automatically renews the SSL certificate with Let's Encrypt, lately the mail portion isn't working, even thought it shows a valid certificate.

HTTPS still works fine.

But if I go into WebServer Settings -> SSL Certificates, and hit the blue button to 'Renew Now' then the mail clients connect without any invalid SSL certificate.

Again, it's only happening on Renewals.

I like @Netino little CLI script to do what the GUI does above.

But I need to figure out this problem/bug, it's not good when clients calls and says their email isn't working due to this problem.

I think I noticed this on one domain on one server. Waiting to see if it is consistent and repeatable...
