Hi Kern..
I have success installed Mail Server at mail.mywebsite.com , but somehow, it's show like this.

it's only can't access site mail. But, i try test in thunderbird it's not problem. I can send and receive email from others.

Ok. We look others in panel, everything is working fine.


Ok, it's Database?, we look it then. It's Gone, no one database name "mail".

PS. It's must 2 database name with mail prefix. but' it's show only one.
But some how, i never try to delete database mail, but, i see on log, my account has been deleted.

Ok, then test mail box, it's working for reply message For the #1 sending failed.

Ok kern, I have no idea what's going on in aaPanel here, can you inpsect then kern?
Thanks for your attention kern.
