There is one special group that will suffer from that decision: namely
SpamAssassin users within your network.

If they do report their spam to SpamCop using SpamAssassin's own report
mechanism, they are screwed. SA does not AFAIK support smart host
configuration, but sends directly to SpamCop. And if it did, and used
your SMTP relay, the report might be stopped by your own SA check!

This group is a minority, but it is where I am.
