Directories with these names are not allowed in Maildir

Hi, Right now, when someone try to create an email filter, cPanel always show error notification. Directories with these names are not allowed in Maildir directories: [list,and,_*]. The condition: The email account was transferred from another non cPanel server using imapsync. The folders came with the email account. The transfer itself was successfully without any error. What should we do? I see nothing wrong with the steps taken. - Removed -
