Greetings all,

 	I've set up sendmail to reject incoming messages with a 554 error if 
they are listed in by sticking this line in my file:

FEATURE(`dnsbl',`',`"554 Rejected " $&{client_addr} > " 
BLACKLISTED found in"')dnl

 	Now this list tends to get mad a AOL and Hotmail mail servers for 
obvious reasons and therefore ALL mail from these domains, legit or not, gets 
 	I'm trying to figure out if a sender's address is specifically 
whitelisted in MS *AND* their server is on if the sender will 
get rejected or allowed for delivery.
 	I'm betting the Sendmail reject comes first in the process, but I'm 
asking those in the know to be sure...
