Thank you, Ben, for your excellent assistance. That is exactly what I needed - and then some. In response to your statement, "I have discovered painfully that as few as 2 complaints by AOL users in 1 month may cause AOL to block mail from my server.", let me say that you are absolutely correct about this. If you do not send a large quantity of mail to AOL from your IP, a few spam complaints can tip the balance of your good-mail-to-spam ratio against you in a big hurry. AOL's policy is extremely hard on small companies, who lack the resources to follow-up on each and every spam complaint. Yet, if you do not do so, your good-mail-to-spam ratio will put you on AOL's blacklist. The repercussions from this are not just a bit of inconvenience - customers close their accounts when they cannot get their mail delivered. It can be absolutely disastrous. I understand AOL's reasoning for not providing the complaining subscriber's email address to the list owner. Subscribers would likely fear reprisals for making complaints. Problem is, their system ends up going too far in protecting the customer's privacy. By not providing this information to *anyone* involved, they are facilitating the making of false spam complaints. We have already had an incident on a busy list, where one of the subscribers became upset with the group, and took vengeance by clicking the report spam button for every list email he received. He thought it would cause the list to be shut down and contacted us to find out why it was still up-and-running (which is how we found out what was going on). Of course, the list was not affected in any way, but we ended up being blacklisted. I would imagine this sort of thing happens with a fair amount of frequency. With that, I'll drop the subject.
