There are also some nice extra features included with this package that can make life a little easier. ICE also gives you the ability to use canned replies and filters. While I myself have not used these features all that much, the way they are implemented is very straight forward. The filter allows you to automatically sort your messages as they arrive and do any number of things as a result of receiving certain messages. In the meantime, you will have to live with the fact that most of the options in this area are still disabled because the code to support them is just not there yet.
Templates are also widely used throughout the program.
In fact they are so integrated, you won't realize you are using them until you start digging to find out how and why your e-mail messages look the way they do. A template specifies what basic things show up in all of your messages. They exist for new messages, replies, forwarded messages, and more. Eventually, you will be able to create and use your own in addition to modifying the ones provided by default. Template processing is how ICE allows you to have multiple signature files, attributes, and many other features.
