Well the emails are being sent to server under different resellers on cpanel and each reseller has different IP and domain setup.
So the mail that was sent came from reseller #1 with one domain and IP.. then aol rate limited that ip so exim queued reseller #1 mail.. then reseller#2 sent some mail from his domain and IP to the server. Reseller #2 ip was not rate limited by AOL and Exim delivered Reseller #1 queued mail over the unblocked ip of Reseller #2.
what so u need to see my exim.conf?

This creates all types of problems as its totally different customers sending this mail and there spf/domain keys are mismatched. In addition they shouldnt be able to effect each others delivery. In theory, Exim should keep the queued mail there in the system till that ip is unblocked or return the mail as non deliverable after X attempts.

I need to see the actual configuration being used to know, since you
describe some observed behaviour but not the configuration which it
might be matched to.
I somewhat suspect that you have same_domain_copy_routing turned on,
which is not appropriate where different mails for the same domain can
need to come from different transport instances.
