I think that it simply connects to the smtp port of the mail exchanger and emulates an email delivery, aborting halfway. Basically it wants to determine whether the mail exchanger would accept email for a given domain. In most cases it won't give you 100% certainty that the email addy is legit, but at least you know that the domain part is not faked, and there is a mail exchanger willing to serve it. -- Arcady Genkin i=1; while 1, hilb(i); i=i+1; end
