Yes, at under 12 cents per user per *year* it's definitely worthwhile in
my personal opinion... I know several providers who have taken their
commercial service either because they wanted an SLA or because they
were contacted by Spamhaus because of their traffic levels....  that
price is rough and totally depends on how many email accounts you've

I believe you can pay them a small fee and do a zone transfer so you are
not hitting their name servers.

If you see value in the service, it should be worth the small fee.  And
since you are hitting them a lot, I have a feeling that you see value in
the service.
