I tried to telnet to mary.iia.org, and a Sun machine named "mary" did answer; I didn't play around with telnetting to port 25 nad seeing if it did smtp, though I'll try sending mail to bogususer@mary.iia.org and see if it bounces. As Steve points out, sometimes credit cards are more useful for services like this than digicash is, but I'd still prefer not to send credit card numbers in cleartext, even if the card vendor is supposed to eat most of the fraudulent use. Would be nice if they'd use some sort of public-key mail system so that they're the only ones capable of fraudulently using the card number, rather than any eavesdropper :-) Bill Stewart
