Some won't bother, you'll lose. A) Greylisting doesn't need to involve any extra work on the sender's part - only the normal retries that all standard mail transports provide. B) Even among people that use email in business, few need to accept time-sensitive messages from unknown senders. That is, you might have sales and customerservice aliases where it is worth wading through the spam to avoid missing a new contact but it would not be necessary for every email address in the company. -- Les Mikesell les@xxxxxxxxxxxxxxxx
