We have an Exchange 2003 server and our e-mail flow in and out is fine except for any e-mail sent to AOL.  Our queue is has dozens of e-mails that say the connection was dropped by the remote host.  We have request a Whitelist addition with AOL but have not heard anything.  Is there anything else we can do?

Please have a read of my article about this sort of problem and make sure you have everything in place, including Reverse DNS:

also worth checking is whether your domain/IP is on RBLs somewhere.

If you have Reverse DNS setup - does the FQDN correctly resolve back to the IP Address you are sending from?

It does alan and checking that link now. We had a spam attack on Monday so we are finding hits of us on some of blacklists.  It does not show how to take ourselves off the ones that come up.

Which ones are coming up as listing you?

Some you can de-register from - others you will have to wait for them to de-list you after a period of time.

For now - you can setup a scoped SMTP Connector for the AOL domain and you can configure that SMTP Connector to send mail to your ISP as a Smarthost.

Once you drop off the Blacklists, you can delete the SMTP Connector and hopefully AOL will be happier with you by then.

Not heard of most of those Blacklists before!

Have you tried www.blacklistalert.org ?

Not one I would expect AOL to be using, but you never know.

What is your score on www.senderbase.org?

Comes across as Neutral.

Good.  I'd try the scoped SMTP Connector for now via your ISP and then wait for a while.

You may need to ask them to allow your emails through - but I would wait a while before requesting that if after 30 days and you removing the SMTP Connector, your mails to AOL still fail.
