This happens because turning on Org mode runs org-load-modules-maybe,
which by default loads ol-gnus, which loads gnus-util, which loads
rmail.  And loading rmail unconditionally adds rmail-after-save-hook
to after-save-hook.

Does this produce any problems in practice?  If so, can you describe
those problems?  Alternatively, you could customize org-modules to
exclude ol-gnus and ol-rmail, if you don't need that in your Org
related workflows.
