Hi, is the problem solved?

aaPanel_Kern dear we also see same can't find Roundcube on my panel mail.eetkt.com

Hello, I suggest you describe the problem in detail. You can find one-click deployment in the app store, or deploy manually

I have installed the roundcube on aaPanel but the link of the domain didn't launch "mail.mydomain.com"

Hello, I don't understand what your problem is? Please describe your problem in detail.
