I bet you've never tried notifying server admins about anything?
First of all, there is no generally accepted admin e-mail address, apart from postmaster. You can also get some information from whois (both domain and ip address) and dns SOA record, and abuse.net
But anyway, most of the messages addressed to postmaster bounce. That happens often to other admin addresses you've found as well.
Of those messages that don't bounce you won't mostly get any feedback at all, they won't even fix the problem you've reported. Most likely nobody reads the message, or understand the language you're using (most of the world use something else than English as their primary language), or even if they understand the language, they don't understand what you're trying to tell them.
When you do get a response they accuse you of either attacking them, or spamming. Well, with spamming they really do have a point, since you're sending unsolicited messages that are essentially similar to multiple addresses.
So basically the blacklist operators are better off not notifying the listees unless they've previously arranged something else.
So, what should the MTA operator do? Setting up automatic polling of the key blacklists is not hard to do. Keep eye on the outbound queue. If the volume you're sending is big enough you'll notice pretty fast if you're in one of the popular ones.
Well, this is really ingenious, blocking empty null Return-Paths. Not only you get all the fake bounces, you get all the other valid NDRs as well.
Of course, if you're not interested in whether your e-mail had bounced or not, this is ok. But why bother to send it in the first place?
The Linux logic is way too different from that of Windows and new users first have to forget their Microsoft ways. And they will only do so if they are *very* motivated or if you show them how to do stuff. Those users obviously aren't tech savvy or else they probably wouldn't have much trouble with Windows or would have switched to something else on their own. My mom and dad (both around 65 yrs old) got their first linux (Ubuntu) machine in November, after using Windows for over 5 years. No, they didn't install it, but they didn't install their Windows either. They might be able to, but then again, might not.
Their comment is that Linux is easier to use than Windows. They use e-mail, browse web, phone with skype and write an occational document.
So, Linux is not necessarily hard from user point of view.
My employer (a university) routinely ends up on blacklists because of students/departments/whatever that don't patch their machines and end up being used as relays.
So, your staff makes a mistake, somebody notices and enters the IP in a blocklist. Suddenly _blocklist operators_ are a*holes?
Hmm. What an interesting world you're living in.
Within 10 minutes, a computer calls the phone number and reads a short list of randomly generated numbers.
Right. And the check would be done in every language from English (different variants of it) to Urdu? Also, let's hope the person isn't hearing impaired.
The user receives the letter and enters that data.
Let's hope the person is able to read the instructions.
In the US, the social security office only wants to see your (or *someone's*) birth certificate
Now I understand. I don't know how to break this to you gently: not everybody lives in the USA.
Some of us are able to use their calendar, be it computerized, mobile phone, pda or paper version, to notify themselves of the domain expiration without any help from a registrar.
Not me, though, but I'm certain such persons exist. Or at least one such person.
Hmm.
Huh?
Spam = unsolicited bulk/commercial e-mail
I don't care what you're pushing. If I didn't give permission, you're spamming.
Snail mail is a totally different animal than e-mail. Snail mail costs the sender real money, thus they pay attention to who they're sending to. A computer parts dealer in South-East Asia will not start sending snail mail ads to Espoo, Finland. They do send them via e-mail.
You forgot one:
Market segmentation
The price of the goods differs from country to country. Of course companies want to protect their bottom line. What the market will bear pricing works only because of this artificial segmentation of markets.
1) You'd give him warning. 2) You'd give hime time to change. 3) You'd point him in the right place for instructions on how to change (for the better).
Have you actually ever tried to warn somebody who runs a server in ip addres x.x.x.x about something? Although it is easy to say that you should warn it is often next to impossible due to a few factors:
1) the system doesn't accept mail for postmaster (or the message doesn't get read and/or understood)
2) rDNS is totally wrong
3) whois information about that domain and/or netblock is wrong
4) you get accused of spamming if you do manage to get your message thru.
As for the time to change, well, is it reasonable NOT to tell others that the guy is running open relay? Remeber, the system spews all the time before it is fixed (and the others have to deal with the spewage).
Many (if not most) sites that run dns based lists of open relays do have pointers on instructions for how to fix the relays.
In my experience the only sure way to get the admin notice is to start bouncing messages. And that even doesn't work 100%.
orbz.org requires one substitute MAY NOT in the RFC to avoid an eventual listing in their service.
Interesting. I've submitted several of my mailservers for orbz ot test. None of them have been listed, although each one of them will return an error message to the sender if they run into an error (like recipient address doesn't exist).
