Out of these 200+SquirrelMail plugins in the inventory, following is a list 10 of SquirrelMail plugins which I have found noteworthy.

This eliminates the duplication of certain functionalities throughout many plugins. It also provides the functionality to check whether the plugins have been installed properly or not.
