500 5.5.0 Syntax error - line too long

[Mike]

We sporadically get these messages from users trying to send to our Exchange
Server (2003). It only seems to be from users that have AOL accounts and no
one else. Any ideas?

while talking to mail.XYZ.com.:

Hey Mike - Did you ever figure out a resolution this? I am experiencing
the exact same problem with only AOL as well and can't seem to pinpoint
it.

Thanks!
