The advise I've seen (iirc it was in rfc-ignorant lists) was not to allow send the mail to abuse and non-abuse mailboxes together, e.g. when it's sent to abuse mailbox, reject rcpt to:non-abuse mailboxes with temporary error and vice versa.
This is what we're implementing for our abuse addresses, using MIMEDefang with sendmail.
The temporary errors are 452 4.5.3, the same codes as for a normal RFC 2821+3463 "too many recipients" error, so any working mail server should retry the rejected addresses.
