Filtering with Procmail before it goes to spamassassin.

I'm new to the list, so please be kind. :-)

I have been using Spamassassin (SA) for my domain and it suits my needs. Lately I have been getting a lot of spam spoofed bounced e-mail using my domain. The spammers don't use a valid user name from my domain, so I can't simply add them to the SA blacklist. I decided I only want e-mail mail addressed To: me@ & webmaster@ be allowed through. Everything else can go to /dev/null. However, if someone has a typo user name as legit e-mail to my domain, I feel they should get a reply letting them know that their 'typo' doesn't exist. At the same time, I don't want to have it reply from a valid e-mail address since it must just get added by spammers and I really want them to send it to a correct e-mail address (perhaps noreply@ ?)

I assume what I described above is a good task for Procmail? I'm still getting up to speed on Procmail and would like to find examples of what I described above done, so that after Procmail does its job, it then passes the properly addressed e-mail to SA.

Thanks in advance,
