Black listed space is a real problem.
It was easier for me to just do a day of whitelist campaigning when I
moved into black listed space (TWTC)and I have not seen a problem since.
But the black listed space is a real problem and if you don't want to
play the whitelist game, or don't have the time to monitor your bounce
traffic so your always ahead of your users problems, (I have so littlie
I do it manually) then it may be worth it.  My company only sends,
maybe, 10k of email a month and receives less then 20k.  In addition I
only had about 15 ISP's that blocked me and the bigger ones all have
impersonally whitelist request sites (Oddly enough, AOL's is the best)
so it was just not worth it to pay for some one else to solve this
problem, real though it was.

David, thanks for your many answers.

A couple potential benefits (but not necessarily for you) could be:

- organizations don't want their own mail servers to be accidently 
blacklisted or somehow otherwise punished because one of their 
clients/members/employees sends some email (spam or legitimate) that is 
flagged by someone as spam. So they put the burden on their outbound 
relay. (Maybe that could be expanded by some to consider "legal" 
responsibility for mail sent from their organization.)

- some organizations are behind IP space that is already blacklisted so 
use third-party relay (for example some Verizon FIOS networks are 
blacklisted and also Verizon's own SMTP relays are blacklisted by some).


Anyone else have thoughts on that? (Or my original questions?)
