Major AOL Spam / Exchange Issues

[mikedealer]

Here is the situation as im sure many of your sys admin's have come across already. It Seems, at least from what i understood from the aol postmaster i talk to on the phone, that aol now blocks ALL email coming from a dynamic IP address and a exchange server. So basically i have to change the MX record to one of my other mail servers (simple pop3 webmail) and i am trying to Setup Exchange to only allow people to use internet email and nothing else, i changed the transport in outlook locally but it still goes out through exchange, Does anyone have any ideas how to turn off the proper email services for exchange to allow users to only Use Internet Email to send and recieve mail?

I Did get it to work when i setup local PST and internet only mail settings but thats kind of pointless.
Any Ideas or insight/experience on this aol/earthlink/yahoo mail nightmare would be greatly appreciated

I don't think AOL is blocking incoming mails from Exchange Servers or email clients under Exchange. You don't necessarily need to change your settings until you test it yourself sending to an AOL account.

From what their postmaster tells me, any dynamic ip address with a mail server, aol blocks all mail. And i cannot send any mail to them whatsoever from 3 different clients i maintain. SOmetimes i get a returned mail, sometimes i dont, but they never go through.

mikedealer,

Couple of questions:
Are your clients ISP or internet connection is thru AOL? Is Exchange Server being hosted on a machine with AOL internet connection?

mike,

don't trust what he says until you check other possibilities. If your ISP has an open relay on it, your emails won't get through cos AOL ban the whole ISP... lots of people have been stung by this.

check that first.

Messages sent to AOL are blocked if originating from a dynamic IP address. One solution: Route e-mail going to AOL through your ISP's "smart host" (which should have a fixed IP address).

I have the same problem, I read that AOL does a reverse lookup on the mail server and the dynamic address doesn't match. The solution I read was to do a smtp relay through your ISP. O.K. fine...How do you setup an smtp relay? I do not know. What parameters are required from the ISP? I use exhange as part of Small Business Server which has a setup wizard what is ello?
