They could quite reasonably be retitled 'Warning' since they sometimes
indicate a disagreement between notmuch and the MDA as to how mail files
should be formatted on disk).  Your case just happens to be on the
harmless end.  I could imagine more levels of quiet, but I don't know if
it is worth the trouble.

I can duplicate that here. Could it maybe a wrapper script or hook
invoked by notmuch new?
