Ie, keep an 8k or 16k or whatever-K cache of email addresses. If the address already exists, don't send to them again. Make sure your initial autoresponse states that fact. An example of this via procmail, is in the procmailex man page. >Any and all suggestions appreciated. Well, maybe not *all* suggestions :) Be sure to put in a twit file ability :-) Jason Fesler owner of the now-dead "infobot@infomania.com" autoresponder/service agent
