On Cpanel Server, i was getting following emails from few of the sites

Cpanel Software Security Notice - Script installs need upgrading

Hello root,

In order to protect the security of your users' websites, we recommend that you
upgrade the following scripts installed via the "Scripts Library" in the cPanel interface:

[manobiz]
- YaBB.0 v2.1
    Location:  at http://mano.bizhat.com/bk/
    Latest: v2.3.1
    Upgrade here: https://server46.hostonnet.com:2083/frontend/paper_lantern/addoncgi/cpaddons.html?addon=cPanel::Bulletin_Boards::YaBB&action=upgrade&workinginstall=cPanel::Bulletin_Boards::YaBB.0.yaml

But this script is no longer present in the server. So don’t have to upgrade it, but these email keep coming to server admin.

To disable mails for script installs that is no longer present, you have to delete the .yaml file corresponding to missing script installs from users .cpaddons directory.

In this case, i deleted

root@server46 [/home/manobiz/.cpaddons]# rm cPanel\:\:Bulletin_Boards\:\:YaBB.0.yaml*
rm: remove regular file `cPanel::Bulletin_Boards::YaBB.0.yaml'? y
rm: remove regular file `cPanel::Bulletin_Boards::YaBB.0.yaml,v'? y
root@server46 [/home/manobiz/.cpaddons]#
