Putting your domain's addresses in whitelist_recipients pretty much 
defeats the purpose of spamdyke.

Putting your domain's addresses in whitelist_senders would create a 
nearly open relay, allowing anyone to use your sever as a relay by 
simply knowing one of the addresses. Very bad idea.

Something that's counter intuitive but very effective is to *blacklist* 
your local domain(s) in the blackist_senders file, as such:
@mydomain.com
Since all of your users authenticate (they do authenticate, don't 
they?), they pass through spamdyke (or better yet use port 587). Anyone 
attempting to spoof an address at your domain is blocked. This 
accomplishes what the reject-identical-sender-recipient is intended to 
remedy and then some, while still allowing users to send email to 
themselves (which I have a few who do - there's no good reason they 
shouldn't be able to). This works like a charm.
