If it's sendmail, you could add a tempfail message (I think) like so:

netzero.com   421 Temporary error - Please call +999 999-9999 for more 
info or e-mail stevesgmailaddress at gmail.com for more info. Mention error 
code #PEBKAC when reporting.

I've had to do these things sometimes in order to weed out (and 
whitelist) legitimate addresses from otherwise spammy domains / ips.
