Mail server error:

aaP_formagiu.catalin

Hello team,
I've added my domain to mail server under mail domain, everything is correct, dns is integrated with cloudflare dns.
When I go to mailboxes I get the following popup with the error:
Something went wrong, an error occurred while running [Mail Server]!

I've tried the fix from Home, server restart, uninstall and install mail server, I get the same error, any ideas?

Thank you, have a nice day.

Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
It is recommended to fill in the following

I've resolved the problem updating to 7.3.5 for mail server, by default the version 7.3.4 is installed, manually you need to update the app list and then the 7.3.5 appears.
Now I have another problem when accessing web mail, when clicking web mail -> public access -> mail.domain.com openes in a new tab but I get:
Oops... something went wrong!
An internal error has occurred. Your request cannot be processed at this time.
For administrators: Please check the application and/or server error logs for more information.

Hello, it is recommended that you check whether the PHP of this site starts the Mbstring extension

aaP_formagiu.catalin

Hello,
information a little bit vague, but I managed it finally, basically I've opened the App Store, searched for php that it's installed, settings -> install extensions -> mbstring -> install.

Thank you, have a nice day.
