As I understand it, the blacklisting services look NOT for large volumes of mail, but substantial and/or sudden changes. I had a spammer get through my defences once and set up hosting with me. Immediately he started sending volumes of email. Within 24 hours our ip addresses were blacklisted, and the advice I got when i tried to get them unblacklisted again was that there was a sudden increase in mail and that's what triggered the blacklisting. I have other clients I host who send more emails than that person did in the short time before we shut him down again, and there has never been a suggestion of blacklisting them. I'm assuming that's because they have built up the volume over a period of time so their pattern hasn't changed dramatically.
