Summary: At this time,uce.elis mostly of historic interest and probably should not be used for spam reporting. I (the author) don't use it for spam reporting myself. I no longer maintain the code. The new maintainer is Detlev Zundel. My best advice today, if you're looking for a way to automate spam reporting: use SpamCop. If you're interested inuce.el, you might also be interested in my ideas on reporting spam.
In 1996, I've written a little utility uce.el that
makes replying to UCE easier. RMS included it in GNU Emacs (so you
have it on your hard drive if you have Emacs installed). The utility
was a blow in the fight with spammers. I hope it was useful. Since
then, spammers' techniques have changed dramatically, as has the state
of the art in reporting spammers' activities (new resources like
whois.abuse.net and value-added services like Spamcop
have appeared).
In 1996, uce.el would send the message I'd want to
send--to the parties I wanted to send it to. In 2000, it sends
unnecessary boilerplate that explains why spamming is bad (as if those
who would take action against spammers don't know this already), often
to parties that are, in fact, innocent bystanders. And the actual
responsible party would not usually be detected.
I don't use uce.el myself anymore (I use Spamcop to
report all spam incidents at the moment; not that I am completely
satisfied with it, but it's better at this time that the alternatives
I am aware of).
Doanload: the last version of
uce.el produced by me in September 2000. You should
probably use a newer version that comes with Emacs, if at all.
