BTW, you can register you server with AOL and they'll not block but send you a message showing where an AOL user complained about your mail. I registered my server with AOL and they do run a pretty professional operation. The postmaster really does answer the mail at AOL, that's more that I can same for most ISPs.

Probably never if each person was getting a separate, tailored e-mail message. The number of messages sent generally has nothing to do with getting blacklisted by Spamhaus and others. Most of the blacklists look at the content and not the process.
That said if you are trying to send the same message to 400 RCPT TO addresses and it looked at all spammy then you're getting on at least someone's blacklist. ;-(
