I will second that using a real MLM is usually a much, much better option that will allow you to prevent collateral damage to your mail reputation when there is a delivery problem. For example, when using the aliases option, you should only allow the one address/user to send mail to the alias or you open up an avenue for spammers to abuse your system. Regards, Ken
