Maybe you are getting an I/O error. By default, rsync skips all
deletion of destination files when it gets an I/O error on the source,
to avoid erroneous deletion of destination files if the I/O error caused
them to be omitted from the file list. (This is a very blunt measure
and making it more granular would be a good enhancement request, but
really the user should address the cause of the I/O errors.) Look at
rsync's output to stderr, and also look for a message "IO error
encountered -- skipping file deletion".
There are always a few errors, like "file disappeared" and the like
since this is a live system (and mailboxes no less, where content is
always changing).
You may wrap rsync with a wrapper as outlined at the link below.
However, keep in mind that you may actually want to be told about such
errors The wrapper could be altered meet your requirements :

I'm not sure that will work - it's a wrapper so it can't alter how rsync
decides what to delete, right? The process of bailing on any deletes when
an error is encountered is internal to rsync, correct?

After looking at the output on your system listed above, it looks like
the wrapper at the link listed above may not cover your issue. Perhaps
you have a different version of rsync or maybe there is a problem with
your file system?
I have some ideas what the "bad file descriptor" is about, and in this
case, I believe it's akin to the "missing file" issue.
Thanks,
Charles
I hope this helps.
