Mail server error

I need advice. I want to set up a mail server on Aapanel and when I give the Mail Server settings, this error pops up and I don't know what to do next. How to solve it? This error appears after I updated Aapanel today. It worked before, but not anymore after the update.

You can try:

Click Update App List in the App Store. If does not working, move on to step 2
Go to Home Tab > Click on Fix at the Top Right of the panel page.

Hello, is it possible to try reinstalling the mail server?

I did both and it still doesn't work no matter how I try to do it, nothing.
