btw, to further elaborate his complaint is that tmda trusts the From
header and uses that for an automated reply. now if tmda was unique
in that behaviour i'd understand. however, here's a list of a few
mail software packages that trust the From header enough to send an
automated reply:
sendmail
postfix
exim
qmail
procmail
deliver
mailman
majordomo
listserv
note that only the mailing list software limits the number of automated
responses.
what karsten really dislikes is that challenge/response changes the
way email works. it makes it a bit less friendly. and i find that
depressing too, but spammers exist in huge numbers and keep spamming.
his constant care and feeding of his content based spam protection makes
him think that millions of others should do the same since it doesn't
really change email (though silently dropping mail isn't a good thing).
in my opinion c/r systems are an acceptable compromise between a central
registry of authorised mail servers (with associated costs and worrying
authoritarian issues) and the chaos that exists today. an even better
compromise would be if everyone pgp/gpg signed email coupled with a c/r
system and a way to query mail servers for valid user pgp/gpg keys.
but i live in the real world. and in the real world most people don't
use pgp (and in fact several people complain about people who do use it)
so i use tmda. and i drop all mail from karsten m. self.
