Hi, Imail will call Declude AFTER it has completely received the message. That means you're stuck with all these junk messages. The best you can do is DELETE or HOLD them, but only AFTER you scanned them all.
So with Imail+Declude you are only saving the time it takes to "deliver" the message into a mailbox. But, that's probably not a net saving in processor time, because I would guess it takes AT LEAST at much time to scan a message and perform all these tests that it would have taken to move the message into a mailbox. Declude is not meant to save processing cycles, it's meant to reduce work hours spent by end users reading/handling spam message. If your current box can't handle the load, than the ultimate solution is more processing power - either by upgrading the box, or by delegating some of the work to a gateway.

So I understand it can not be done to reject invalid senders simply by using Declude/Imail? I really need another product? Also another question: I use per domain configuration for Junkmail - can it be configured so that it only performs the tests on mails that go to a domain that has been set up with a configuration folder? It seems like declude is doing the tests on all mails which uses more ressources than doing the tests only when required (as defined in per domain config) Thanks Andy Schmidt schrieb: > Hi, > > Basically, you should put a mail gateway in front of your mail server > that can integrate your list of valid email recipients and that can > refuse most of your messages based on your anti-spam and anti-virus policies. > > One option would be to run Declude's own gateway product. > > However, to me a crucial element of a gateway is that it MUST reject > messages DURING the SMTP envelope (e.g., after the data is received > but before the receipt is confirmed with a 2xx.).
