Hi,
I just realized that uu.net (appear so me to be an ISP) has many spamers are their clients. I am wondering what is the solution to this. If a spammer will signup for a account from uu.net then he can authenticate himself and send spams to many people. How can uu.net stop this? It appears to me that uu.net is listed as a spaming domain (sorry for this slang language but I do not have the proper term for this) and mails from this domain are not accepted if we disable the mail delivery from blacklisted domains. How can I as a sysadmin make sure that uu.net spams are not welcomed but genuine users from uu.net are no problems. Thanks in advance.
Bye.

Also how do I prevent any of my clients from sending spams. Setting a limited number of receipents is an obviously a temporary and broken solution, any other suggestion is welcomed. Thanks in advance.
Bye.

Please correct your line length ...
What you need is some kind of spam detection like SpamGuard. It scans every incoming mail for a certain number of features that will identify that mail as spam. Works most of the time, but there's no guaranteed way to recognise spam. Some legitimate mails may be marked as spam while some spam may get through.

The OP, Please note that this opinion is of the individual and not a rule of the list. Personally I dont mind it. Some other dont. Some other do. So you can decide on your own.

I would suggest you to read the start of the document carefully. Also check your local English dictionary for the difference between "Guidelines" and "Rules". Get back to be after you have done so.
Thank you for you co-operarion.
quasi p.s. From one human to another -> This world is full of change and is always in flux. So I think hard before I form any opinions. Then I also do not mind changing them when they are shown to be inferior or faulty. But I /do not/ accepet things blindly. So please give convincing reasons for the line breaking and not the ones in age old documents which I have already read and found insufficient.

If I have to reply to someone's mail, I prefer to snip out irrelevant portions of the mail and quote only relevant portions. I hope no one disputes this point.
If a line goes beyond 80 characters, it will wrap automatically. I will have no problem reading the mail. Any good email client will do that for you.
When I hit reply though, the email client needs to make a decision. Does it display long lines as they are, or does it insert hard line breaks near the right edge of the screen.
If it chooses the latter, then it is modifying the original message. This could cause lossage when the original message actually required lines longer than the screen width (eg, source code).
So, let's assume it does the former.
I now need to snip off irrelevant portions of the message. The easiest way is to delete all lines that are not relevant, and leave the rest.
But... the entire message is on one long line. What do I delete? I'd have to navigate my cursor to the position within the line where I want the deletion to start, and then delete until the position where I want the deletion to stop. Too much work for someone who's offering free support. Most people would rather just quote everything - and then get flamed for it.
There is another solution. An editor that can navigate through the message by screen lines and not by actual lines. It should also be able to delete screen lines.
There's a new problem here though. If the lines were long to begin with, then deleting a portion from the innards of the line leaves a line that may not make sense. Take for example (assuming screen width==15c)
Hi luggers my sound card doesn't work. What should I do? I have a Yamaha card.
wraps to: Hi luggers my sound card doesn't work. What should I do? I have a Yamaha card.
would snip to:
my sound card doesn't work. What
[snip]
Yamaha card.
But, since the email client shouldn't be automatically adding line breaks to someone else's message, this line is actually:
my sound > card doesn't > work. What
[snip]
Yamaha card.
Which will cause problems when the reply is replied to.
If everyone has a line length of approx 72 characters, it allows for up to three or four levels of quoting. Sure, lines will get smaller as they go along, but that's a Good Thing, without which, the Story of Mel wouldn't have quite the same effect.

I agree with you about the excellent example you have given. Indeed it would be wonderful if we all had 25x80 terminals and dedicated email accounts. But most of us don't.
I would have loved to give a detailed reply but I fear it is past 1am. But I hope the few points I detail below show you the other side too.
#1. If you have had the misfortune of using web-mail you may have notice the various strange and rather extreme behaviours they sometimes exibhit.
#2. The 72 lines wrapping gets broken when viewed with anything narrower giving a harrowingly unnerving effect. The replies get even worse with some webmail clients.
#3. I believe that maximum flexibility should be given to the /user/ to decide what/how his messages look. If given a long line, for example, I can make use of the new(sheez) higher resolution displays to display up to 120 columns. I can, if I want, fill the "long" lines (like this particular email). I can fill the original message too, with only one command if it is painful (so your "/I/ am helping so /I/ rule" goes down the drain). So you see, with minimal effort I can make things the way I want them to be. The other person has least trouble.
#4. If you believe in real freedom you should not harp about things which /you/ are used to. Someone else may not actually mind trimming all the words in a long line one by one. Posting styles even if they are irritating are not actually causing any harm. Large amounts of unwanted/irrelevant/untrimmed material /does/ cause wastage of resources and hence harm. Also I again point you to #1. & #2. which often go together.
#5. Until recently I have been using Eudora which AFAIK does not wrap(fill) lines. I don't recollect anyone having any trouble over it at all. I have over 2 years of ILUG-BOM correspondence with me.
If everyone has a line length of approx 72 characters, it allows for up to three or four levels of quoting.
Like here, even if you fill the lines, I have to do a bit of juggling to trim parts which are in the middle.
Sure, lines will get smaller as they go along, but that's a Good Thing, without which, the Story of Mel wouldn't have quite the same effect.
I don't see any relevance of SoM here.

What does line length have to do with the Story of Mel?

uu.net had faced the usenet death penalty some time earlier.

By deleting spammer accounts on complaints recieved. Note that veyr spams come from hotmail and yahoo because they enforce their terms of service.
It appears to me that uu.net is listed as a spaming domain (sorry for this slang language but I do not have the proper term for this) and mails from this domain are not accepted if we disable the mail delivery from blacklisted domains.
Which blacklist? I personally use spews, blackholes.wirehub.net, ordb.
How can I as a sysadmin make sure that uu.net spams are not welcomed but genuine users from uu.net are no problems.
You could try spamassassin, but I'm of the type that prefers to block first and worry about lost mail later. If uu.net is blocked, then people will just stop using uu.net, or uu.net will hunt spammers down.
