[arch-general] Vim Syntax Highlighter

I noticed today when editing a config file for Postfix in Vim that one value was listed in white text only and everything else was in color. This lead me to beleive the value or parameter was wrong or not being recognized by Postfix configuration but it is. I asked Postfix and the said: "Your VIM syntax highlighter is out of date" Can anyone tell me if there is a way to update this manually if I have the latest version of Vim in my Arch repo?
