how is this proof that sorbs 'throws the baby out with the bathwater'?
it looks like a netblock that SORBS has de-listed.

yes, precisely so. they state this quite clearly on their web page.
and for good reason. spammers lie. regularly and repeatedly. why
should SORBS believe some end user who doesn't even own the IP address
concerned? if it really isn't a dynamic IP address then the actual owner
can contact SORBS and have it de-listed.

if you want to do stupid cache-busting things then you have only
yourself to blame for the consequences. e.g. if you get listed in the
SORBS DUL and find it difficult to get de-listed because of your TTL
then you have only yourself to blame.

well then, you finally figured out how to get mail working correctly
from a dynamic IP address - use a smarthost. preferably one under your
own control.

so? you say that as if there's something wrong in doing that. i have
several exceptions to my anti-spam rules for my abuse@ and postmaster@
addresses, but i'm no more willing to receive spam/viruses on those
addresses than i am on any other address. and those addresses get
spammed at least as often as my other addresses - it's not like spammers
make any effort to avoid spamming them...quite the contrary. they seem
to like spamming them, possibly because they are required (postmaster@)
or strongly recommended (abuse@) addresses for EVERY domain.

SORBS DUL is a list of dynamic IP addresses. it should not be
particularly easy to get de-listed, and certainly not because of a
request by the end user.
