I have now had the time to set this up to enable the "mailto:"; syntax. I
agree that the export of the "mailto:"; string as well would be nice to
suppress, but this is a minor quirk. Both \url and \nolinkurl are good
options as well to avoid that.

I also learned that the backslash in the setq must be escaped to avoid
raising an error, i.e. i put in my init.el:

: (setq org-export-latex-href-format "\\url{%s}") 

Many thanks!
