creating a link to the original message, translating months names

I have 2 problems :

1- In each  msgXXXXX.html file, I would like to create a link to the textual
   file containing the original message ; I found no variable containing the
   path of the file.  How can I do this ?

2- I use <WEEKDAYS> and <MONTHS> to translate names of days and months ;
   the days are well translated, the months are not. 

Best regards,

Odile Germès
