That's annoying, and I > haven't understood how two people not on each other's whitelist could > ever communicate with each other if they both uses the scheme. Three ways that I can think of: 1. The first person sends the second person a "dated" email address which allows the second person to respond within (say) 5 days without a cookie request. 2. The first person can generate a special email address for the second person that will never ask for a cookie (if it's abused, the address can be dropped). 3. The first person adds the second person to his whitelist before sending the original message. the second person doesn't reply within the timeout period, then he's probably never going to respond. On the off chance that he was gone for a long vacation, then he'll be inconvenienced by the cookie reply, but that's a one time thing and should be relatively infrequent. > And it looks ugly.) I'll accept ugly if works as advertised. Currently, though, it's only really useful on systems processing their own mail (as opposed to POP or IMAP off another server). Properly configured, it does look like it will eliminate SPAM from your Inbox, but your computer is still processing the SPAM. It looks like a good option for highly connected email servers to offer to their customers (HotMail+TMDA??). -- David Masterson David DOT Masterson AT synopsys DOT com Sr. R&D Engineer Synopsys, Inc.
