There are various "band-aid" approaches, like running the outbound mail through spamassassin and HOLDing the "spammy" mail, however this may or may not catch what you want, since even SpamAssassin has no idea if the user actually wanted the mail or not.
another approach is to setup some quotas for outgoing messages. Try to setup some quota based on number of messages sent in a specific period of time.
This will certainly not avoid the 'small' spamming sending, but could potentially break the big ones.
policyd, for example, can deploy quotas based on SASL authenticated username, email addresses, quota based on number of messages as well as traffic of those, and other things.
again, it will not fix the problem, but maybe avoid it to became a HUGE problem.
