I get the feeling that Denis is thinking of various challenge/response
methods like TMDA, which I also refuse to work with.  I, however, also
don't like address verification for the same reason that I don't like
bogus spam and virus bounces - you're eating *my* bandwidth (and log
space, and cpu time, and SMTP connections, and...) up to make *your* job
easier.  I don't like it when people "spread the load" indiscriminately
and to people who did not offer their resources.  If you get a
dictionary spam flood from someone forging one of my domains, I get a
connection flood from you while your system tries to validate those
thousands of bogus addresses.  Uncool and unwelcome.  Likely to get your
domain blacklisted, at least temporarily, by me.  Not sure how other
people handle it, but that's why I won't use sender address verification.
