Yes, some of your customer's orders might be blocked, just as other legitimate
mail might be blocked.

In general, the best DNS-based blacklists to use for an e-commerce system are
the MAPS RBL and MAPS DUL.  The DUL will block less legitimate mail than any
other list, but you probably need the RBL to avoid the blatantly unrepentant
spam houses.  In such a situation, you will want to be more careful about
using DNS-based blacklists of open relays.

In the end, however, you will proably want to whitelist your customer's order
email addresses.  SIMS can do this quite nicely.  That frees you up to protect
your regular addresses with MAPS RBL, MAPS DUL, MAPS RSS, and perhaps even

If you want confirmed and unrepentant notoriety, look to the MAPS RBL.
