In a previous post (unsolved), I asked about an issue with rspamd which appears to be stopped in the aaPanel GUI, while it's indicated as running when I look through systemctl status. And now, I see that I can't send any email (tried using the "send email" feature in the UI), while all worked fine one month ago (it's a staging server, so I don't use all features every day). So, zooming out, the question is: Does the current aaPanel and specifically its MailServer are compatible with AlmaLinux 8.8?
