I am still here asking and it cannot be otherwise.
I keep getting e-mail alerts like: Failed to obtain SSL, issuing self-signed SSL for: mail.subdomain.domain.com, on all my 15 subdomains. A real nuisance. This used not to happen, now it happens every 7 days. Does anyone have the same problem as me? And if so, how did you solve it? I hope to find your help.
Thank you for your reply, but after checking around a bit I think the problem relates to this: [BUG] Automatic mail.domain.com creation and ssl installation. · Issue #1059 · usmannasir/cyberpanel · GitHub
