Default SquirrelMail plugin list?

Hello everyone,

You will probably laugh at me, but did my own install of squirrelmail because I wanted the functionality of only one specific plugin, however my question is: Is there a list somewhere of the default plugins that dreamhost uses on their installation of squirrelmail? I’ve found some of them but I think I’m missing a large amount of them. Any ideas how to get a list would be appreciated.
