While starting and verifying Mailman service on your cPanel server when you received above message then you can fix it with following steps :
(Note : You need administrator access of your server)

a. Please enter into the mailman folder

root@server # cd /usr/local/cpanel/3rdparty/mailman

b. List files and folders

root@server # ls -al

c. Change permissions of all the folders and files recursively

root@server # chmod -R 2775 ./*

Please verify with these steps that you have fixed issue and you are receiving e-mails.

d. But isssue is not fixed yet then you need to run Mailman script which is inbuilt with cPanel

root@server # /scripts/fixmailman
root@server # /scripts/fixmailman -f

Done !
