changing mulitple email addresses WHM

Are you speaking of updating the contact email on the 80 accounts?

 

You will have to change the contact email addresses individually via WHM or manually modify the contact email address in the following files:

Code:

/var/cpanel/users/$username
/home/$username/.contactemail
/home/$username/.cpanel/contactinfo

Remember to run the following command after modifying the cPanel user file:

Code:

/scripts/updateuserdomains

Thank you.
