Laurence, Firstly, the point to which you speak has never been an issue that we have been made aware of. Secondly, I would be very afraid of doing "major funding" strictly through email. How many people do you truthfully know who routinely run 7-figure deals over email? I think your concern is placed at a higher matter that I cannot address. The only thing I can comment on is that the greylisting system has been in place for several months. We had the idea on the table for several months before we wound up going live. Very few delays have stemmed from greylisting over the past months, but we have done our best to see to it that they get fixed. Other delays stem from numerous issues, our own email system not withstanding (for example, yesterday's slowness due to problems with our NetApp). But I have also seen problems on the sender's side, firewall issues, network issues, and client wonkiness to boot. If you feel your concerns are not being met, I'm afraid you will need to take them to some place higher than this list. I will continue to advise against the impracticality of doing major business deals over email without some other form of communication to be used as a backup. I would never even buy something as little as $10 off the Internet without knowing there was a phone number I could call in case there are problems. If there are further questions anyone has about greylisting I will be happy to do my best to answer them. It is a system that I play a large part in because not too many of my other coworkers care to use OpenBSD. :-) ./brm
