|I've seen this happen before.|
Company has Exchange server with little to no spam filtering. Users want a copy of their email forwarded to AOL. This will forward both Spam and Non-Spam to the AOL account.
The users will then view email in AOL, and the stuff that is Spam they will click on and report as spam back to AOL. This gets your exchange server blacklisted. It doesn't take much for this to happen, a couple users report a couple emails a day, and after a week or two, bam - your blacklisted.
If you call AOL's Postmaster group, and explain situation, you can actually get off the blacklist fairly quickly.
Then, tell your users not to report mail as spam in AOL client, or dont forward, or do better filtering on company exchange server.
No matter how well you filter, some stuff will slip through, so AOL users will always be causing problems unless they completely stop reporting everything.

As I said in the subject, any mail that goes from my server to an AOL email address ends up in the spam folder. I don't have any spam going out, but I think I know what is causing the problem. I host my own clients, and none of them would know how to set up a spam campaign. I have the email for a few of my clients just simply forwarding to their AOL address because they don't know how to set up an email client for themselves. And their email address on my server recieves a LOT of spam, which just gets forwarded to their AOL address. So I think that AOL must think that my server is a spam server. When I look in my logs, I see spam messages to these few clients being forwarded about every two minutes.
I think the same thing is happening with gmail as well. Anything sent from my server to gmail ends up in the spam folder. I have one client who recieves a TON of spam using the gmail trick....forwarding his mail to gmail to use their filter.
I looked up my server, and it is not listed in any of the spam databases. At one point I was able to twist some things around, and get qmail to send from one of the server's different IP address's, and that worked...for a short while.
This also hurts my clients sites in other areas. For example, some of them have ecommerce sites, and when a customer places an order on their site, they may get a an email receipt, or a confirmation message that they need to respond to, which just get's spammed.
Does anybody have any ideas? How can I provide a quality email service to my clients?
