I implemented rate limiting for Exim to address this problem. The feature
is available in version 4.52 and later.

We have a few thousand users who forward email off-site, and it gets the
same anti-spam filtering as locally-delivered email. This seems to be
sufficient to avoid trouble with AOL etc.
