I know you eventually want to block at the MTA level and that this is just a test, but for anyone else considering bouncing this crud at the TMDA level, you should probably just drop them instead. For example, I have 172 messages in pending with an envelope sender from yahoo.com, none of which came from Yahoo. I have verified this by running the IPs of the last relays before the mail hit my machines through DJB's dnsfilter and grepping for yahoo. Not a one of those messages actually originated at Yahoo. Which means every one of the bounces I would generate from TMDA will just get double-bounced, the same as a confirm message would. Save yourself the trouble (and Yahoo's servers the load of telling you the account is invalid) and just drop them.
