Hello admin, allow me to share my experience using Webuzo 3.0 ????
1. Error PERL : if I install PERL, MariaDB 10.5 and EXIM can't running. After that, if PERL is uninstalled, MariaDB 10.5 and EXIM stuck to running normally (before I tried to Install PERL, MariaDB and EXIM run smoothly), I must Uninstall MariaDB and EXIM then Install again so that it can run smoothly.
2. Error DKIM : if I use feature "Tick to add SPF, DKIM and DMARC records in the DNS", DKIM can't create normally, the Record DNS only "v=DKIM1; p=username;" (mean 'username' is username multi-user, is not use random Key for 'p' like previous version), and I tried to send Mail via SMTP/Rainloop feature, there is no email (at Inbox/Spam) to my email (I use gmail for test receiving).
3. Error SSL for Admin Panel : I tried to use feature "Manage Service SSL Certificates" to Install SSL for Webuzo Service, Exim and Dovecot, and it's success install with my own certificate (via Cloudflare). But if I tried to open panel from port 2003/2005, I got a Privacy Error like my SSL can't install normally.
That's it my experience for use Webuzo 3.0.x (6 and 7 ver.).
