I have some stats here that suggest otherwise. We only have 5% more
recipients than messages that make it through our gateway, and we only
return permanent errors presently for mail bombing related activities.
This however is a dedicated gateway and not a hosted mail server, so
stats from a hosted mail server would see a slightly higher rate since
most multiple-recipient E-mails are internal to a server. If you are
splitting on a gateway and not splitting internal E-mail, you should
see no increase beyond my numbers. It's a doable solution if one has the need.

Delcude has always functioned like this. What declude could do in this case is to duplicate the message for each recipient and write a new header file to each recipient. Not a big issue. Deliver to the one that whitelists and run the spam checks for the others.

It's actually more of an issue of how the mail server handles the message. In the case of multiple recipients, since there is only one message file addressed to multiple recipients in the headers, it's either deliver or not deliver unless you rewrite the headers to modify the recipient list. I think I'd rather not have the spam filtering systemalter that. Add to the header, yes. Alter the recipients, no. Also, I have not come across a situation where I wanted to let a message go through to one recipient and not to others, except in the situation of lists which is a whole other topic.

I would call that a flaw, then, in how Declude processes thewhitelist.I have a listserver email address for which I do not want email spam checked. This is because I don't want messages going out to the list that say SPAM in the subject line. Because nobody who is not a memberon the list can post to the list, there is no problem whitelisting the"TO" address for mail sent to the list server email address. However, spammers will send an email to a dozen of our mail addresses (12 recipients) one of which is the whitelised "TO" address for the listserver. Because of the way Declude processes the whitelist, that means that the other 11 recipient receive the spam even though mail to them is not whitelisted. That is a bad design on Declude's part, wouldn't you agree? Anyone else feel that this needs to be rectified?-----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED]] On Behalf OfDarrell([EMAIL PROTECTED]) Sent: Tuesday, October 17, 2006 11:25 AM To: declude.junkmail@declude.com Subject: Re: [Declude.JunkMail] Whitelisting flaw in Declude?
