I have succeed install mail server on aapanel
Let say, mail.sample.com
Then, I install https://github.com/pixelmotor/disposable-mailbox on another shared hosting to create disposable email service with imap address from mail.sample.com
I have succeed too
I can receive email normally

I try to install disposable-mailbox on aapanel sample.com/mail
I have enable imap extension on PHP
I get this error:
