The answer is don't use cua-mode. It works fine when using M-w and C-y and the definition of the macro is:

(fset 'makeMailNoCua
   (lambda (&optional arg) 
   "Keyboard macro." 
   (interactive "p") 
   (kmacro-exec-ring-item 
      (quote ([down home 67108896 19 124 return left 134217847 end 25] 
      0 
      "%d"))
     arg)))

Many thanks to phils. Once the solution found, it's easier to find that the problem was known, see Cua-mode and keyboard macros and has a fix ;)

The answer is don't use cua-mode on Linux, it's OK if you are on windows (but not on wsl of course). It works fine when using M-w and C-y and the definition of the macro becomes:

(fset 'makeMailNoCua
   (lambda (&optional arg) 
   "Keyboard macro." 
   (interactive "p") 
   (kmacro-exec-ring-item 
      (quote ([down home 67108896 19 124 return left 134217847 end 25] 
      0 
      "%d"))
     arg)))

Does anybody knows why ? Many thanks to phils.
