in thread Most of the email spam I get is:

Messages with an enigmatic or vague subject line (that looks like a Markov chain or random dictionary words) and no content -- absolutely nothing in the body at all, no HTML part, no attachment, no nothing. I seem to get a fair amount of this, and I'm confused as to what possible reason the spammers could have for sending it.

Testing if its a valid email address? If it doesn't bounce your email address gets added to the "alive" list.

    I Disagree. They can't reliably get information on what addresses work from the transport mechanisms. The Mail Exchanger (MX) for any given domain may simply be a relay, and unable to tell the remote host if the/a recipient is invalid. If your MX is able to give that information, or is a relay that can do so by using LDAP lookups, I'd be surprised if the spambot actually cared about recording the status of that particular e-mail address (a lead, if you want to make it sound nice).

    Now, in the case that you have a relay, every message will get an OK status when the spambot delivers the message. When the message gets to a host that can say if the recipient is invalid, the relay that was connected to that host will make the "bounce" message -- I'll say "DSN" here. DSNs are sent to the envelope sender of the message. There's a very slim chance that the envelope sender of a spam message goes to some mailbox that tracks the status of leads. That would make blocking spam messages much easier for us Good Guys. Most of the time, they will use an invalid user at a valid domain. Sometimes, the user is valid. That's called a Joe Job, and the user or domain will start receiving thousands of DSNs for messages that they never sent. Not fun at all.

    I think that in this case, it's simply a mistake on the spammer's part. That sort of thing is rather common -- most often, I see messages that have a bunch of tokens that are meant to be substituted before the message goes out, but aren't. I've seen some other stupid ones before, too.

[marto]: "Eugenie Scott, executive director of the National Center for Science Education, dubbed this approach the Gish gallop, describing it as "where the creationist is allowed to run on for 45 minutes or an hour, spewing forth torrents of error that the
[marto]: evolutionist hasn't a prayer of refuting in the format of a debate." She also criticized Gish for failing to answer objections raised by his opponents"
[erix]: one would hope evolutionists haven't any prayers anyway
[marto]: obviously someone could be religious, but not creationist
[erix]: "Nothing in Intelligent Design makes sense except in the light of Creationism" <-- I made that one up myself (free after Dobzhansky )
[erix]: yes. Deplorable marto, deplorable.
[marto]: the situation seemed similar to this one, majority of the contributrions are nonsense, doesn't address any questions ...
[marto]: meh, I've been called worse :P
