That's probably because we give full privileges to users over their
download area :)

Would you consider running '--ignore-errors'?
(note: you might also be interested by --delete-during :))


Independently: I checked the 3 troublesome directories, and they are
empty. I'll just make them browseable. According to my tests, when
only a file (not a directory) is 'access denied', that does not
prevent rsync from deleting files.

However, I think '--ignore-errors' would be needed, even without those
3 troublesome directories, because a user still can, willingly or not,
make a non-accessible directory in his download area, which would
cause rsync to complain as with gnumail/fsf-ams/ruf and skip file
deletions for the whole mirroring (like now).
