Grammar checking

How can I make EmClient checking grammar as well as spelling? I work in many languages and need a closer look at writing as just the spelling of single words.

Unfortunately eM Client does not have a grammar checker.

That is unfortunate. The program is very good and modern with a very good user interface. But working in three different languages every day makes it mandatory to have grammar checking as well. Our company needs to look at other alternatives then. Thanks for answering so quickly.
