Hello,

What webmail are you using? Did you try to switch it to another to check the issue?

Try to reinstall webmail using Plesk autoinstaller.

Check permissions in /var/qmail/mailnames/domain_name/user folder

 

[chktab]

I'll try, can not be verified by the admin Plesk?
In the graphical environment?
Thank you
