Sorry, let me rephrase a bit.  A whitelisted connection can do anything an 
authenticated connection can do.  So if spamdyke is configured with the 
"access-file" and "local-domains-file" options, it will control relaying itself 
and set RELAYCLIENT.  In that situation, a whitelisted connection would be 
allowed to relay.  If spamdyke's configuration is missing one of those options, 
it won't set RELAYCLIENT and a whitelisted connection will only be able to 
relay (unless qmail allows it to do so).

The holdover I referred to is in the way I wrote the code.  Since whitelisting 
came first, I had already coded a way for it to bypass the filters by setting a 
flag as spamdyke is running.  When I implemented authentication, I used that 
existing system instead of creating a completely new code path -- 
authentication sets the same flag as whitelisting, so spamdyke's behavior is 
the same for both.
