Well, I am by now totally p!$$ed off with two groups of people.
One of them is spammers. (If you have lived on Xena for the last couple of years, the Spam Primer is a great resource explaining most of how spam works in easy words -- Randy Cassingham is a genius!) Now, it's not hard to be, ahem, somewhat antagonistic towards this specific incarnation of the scum of the earth, but it's nothing a good spam filter cannot handle.
... Which, come to think of it, is a problem when you have had to reinstall your system and the finely tuned Bayes-filterlist is gone. Like it happened to me two weeks ago. Several mailing lists I am on (and that are definitely no spam -- Elfwood Moderators, for example, or the mailing list for Campaign Cartographer 2) get at least partially flagged by the RBLs as spam, so this will take a while until the auto-whitelisting of senders kicks back in. And only after that, I can think of training my Bayes filter again.
Still, it's something that doesn't come as a surprise.
What really gets me riled at the moment are postmasters that seriously misconfigure their email servers. As in "You get an e-mail that cannot be delivered? Send a reply to the poor sod in the From:-field about this." Why 'poor sod', and why is that bad, I hear you ask?
Simple. With spam -- which according to recent statistics makes up about 75 per cent of all emails in circulation -- the chances are higher that they cannot be delivered than with honest mail. Honest mail at least assumes that people are thinking, sensible beings as opposed to the brainless invertebrates that make a living out of sending spam.
*knock, knock*
Just a mo'

Sorry, I have just been informed by a lawyer for the World Organization for the Rights of Molluscs (WORM) that this is highly objectionable language and considered libel against invertebrates. So, I will in the future refrain from calling spammers 'invertebrates'. Maybe in a couple of million years, when the spammers have evolved far enough to join those ranks, I might re-consider, though…

Ahem. Where was I?
Oh yes, with spam, chances are higher than average that the recipient email address doesn't exist. Mail addresses that were abandoned due to a spam deluge centuries ago, mail addresses that never existed, they all are in the lists of 'valid and checked' email addresses some spammers sell on CDs to train their successors. And then, there are the dictionary spammers. Take a domain you know that exists, and send mail to, say roaca@, roacb@, roacc@... roacg@, roach@, roaci@ etc. You know, just try everything. Just make sure your insertion point isn't in the headers, so you don't get flooded by the 'cannot deliver' messages coming back.
And remember to use some made-up address as a From:-address.
Best use 'valid and checked' addresses to send to, and a dictionary attack for the From:-addresses. Just grab an email from your CD, remove the part in front of the @, and start adding names, numbers, whatever instead.
Get it now why replying to the From:-address with 'cannot deliver' is a bad idea that is strongly discouraged by everyone wise to the ways of spammers and the ins and outs of e-mail?
I guess you realize what is coming. My email is collected through my own sub-domain. It's the Demon-setup where every customer has his own subdomain, and anything addressed to that subdomain -- no matter what is in front of the @ -- gets delivered. Cue ominous sounds here.
The last three days, I have been weeding out more 'cannot deliver'-mails delivered to email addresses like joeshmo28343@mydomain, asdffdjkl@mydomain, i.am.sutpid@mydomain, name.family@mydomain etc. than I get in spam in several busy months. And believe me, I am not someone the spammers leave alone, never mind the fact that I never ever react to spam at all, except for sighing and deleting.
This is, let's face it, more a question of idiot sysadmins not configuring their mailer daemons correctly than that of spammers. It feels weird, defending those ... yes, sir, I remember not to use that word again ... those eejits, but either refusing those messages outright, or sending them to the real sender address (if it can be determined, if not, the message should be dropped anyway), would be the correct way to do it.
Well, writing this has taken me about 30 minutes, guess my mail box is well-filled again with "cannot deliver" messages. Let the spammers all join Vardan Kushnir in whatever circle of hell has been reserved for spammers. My guess: they go to hell made up as little kids, and get dropped into the hell for pedophiles. Double punishment when the latter realize how old their victims were...
