A clients domain has been tagged by AOL and Yahoo as sending spam. In order to comply with their Feedback Loops we are required to implement DomainKeys Identified Mail (DKIM) . I have found where to purchase such an app on the internet but is there a way around spending a few hundred bucks for this license , and still implement this authentiocation mechanism?

I have to say that I have never deployed this for any client. DomainKeys is almost exclusively Yahoo, no one else uses it, and Yahoo simply try to force it. I wasn't aware that AOL used it.
Exchange doesn't support it natively, Microsoft et al would prefer that SPF records are used, which is domain based, rather than server based.

AOL is not implemeting this...only yahoo is making me. It seems that any email I forward to an external recipient (aol or yahoo)in exchange gets flagged as spam by them. Is there anything you can think of that I can look at to prevent this other than creating feedback loops with the ISP's?

By forward, do you mean you are using a Contact?
If so, then that wouldn't surprise me. The forwarding method that Exchange uses makes the message look like a spoof and if the original originating domain has put anti spoofing measures in place then the message will get blocked. The feedback loops isn't going to help with that, because it is not something under your control.

AOL are very picky about who they will accept email from. Can you send email to Yahoo and AOL as new fresh messages from your Exchange server? Do you have everything setup correctly - valid DNS records, SMTP banner and PTR/Reverse DNS records ?

Mestha,

I agree with what you are saying and this is what it appears is happening. I do have some issues with my dns that I will fix such as rdns records. I will attempt to fix these first before setting up feedback loops. Messages forwarded to contact addresses (Oh, yes I am using contacts) intermittenlty show up in spam or inbox on AOL and Yahoo recipient containers.
