I have finally ground to a halt with this problem...AOL cannot help...BT cannot/will not help, they say we have to use their SMTP servers and then it will be OK..!!
Try it. This is your best tactic.
We have a fixed IP address and it is not "Residential" and we are definitely not Open Relay (as AOL confirmed).
You're collateral damage. As Rummy says, "stuff happens". AOL "should" have stuff-handling procedure, but then again, maybe they would also say send your outbound through your access provider's gateway.
I bet AOL is not going to run waste, in their opinion, their resources to admin a whitelist of 1000's of IPs like yours, but they will keep blocking 100's or 1000's of networks like yours, when relaying through your access provider is available.
My only other thought, but I am unsure as to the consequences, is to change my PTR record to be 217.34.127.9 = imail.iesdigital.com instead of it's current "host217-34-127-9.in-addr.btopenworld.com" - would this work or does it have to be BT as they are our ISP.
# dig -x 217.34.127.9

That domain name is enclosed in BT's NSs, so your NS is not authoritative, nothing you can fix with your NS records.
And if AOL is blocking by IP by network rather than by PTR hostnames, changing the PTR hostname would have no effect.
