It's extremely hard to tell, and depends on the _reason_ for
deferrals/failures:
If you run mailing lists that do not have bounce handling, you'll see
quite a lot of failures due to bad addresses. If you run e.g. ezmlm
which does handle bounces, you'll see much less. If you send "bulk
mail" you'll see a lot of failures - the harvested address lists are
often of low quality.
If you have your own/local DNS, you'll see few lookup failures. If you
don't and the connection is variable, you'll see deferrals from this.
If you deliver mailing lists with many messages to hosts that can't
handle it, you'll see deferrals from the recipient host ("can't fork -
out of memory", etc).
