Bates > [EMAIL PROTECTED] > The only caveat with whitelists for recipients is that if you bypass policyd altogether (and otherwise, have no backup mechanism such as postfix' "anvil"), you run the risk of destinations you do trust getting huge numbers of messages in the event they are targeted. How open you want to leave yourself depends on how much you trust your recipients to not be victimized. I've seen this happen with things like mass-mailings where the bounce went back to the sender and the sender apparently had no idea there were so many "bad" addresses in the list. You can, of course, throttle recipient receiving rates via postfix, for example. Finally, I imagine it's also a question of how much overhead is saved by not whitelisting certain destinations. --Tobias ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
