--- Comment #1 from Robert Richmond <bob@???> ---
I had the same problem sending to AOL addresses. Their greylisting setup
recorded attempts to deliver immediately to multiple MX hosts for the same
domain after one of them returns a temporary rejection code as being "spammy,"
even though that's perfectly reasonable behavior. I worked around it by
setting:

hosts_max_try = 1

... in my SMTP transport config. That makes it so that if one server in an MX
list temporarily rejects your mail, it won't immediately retry on a different
MX. It'll queue it, as some greylisting hosts seem to require.
