Hi,
I just realized that uu.net (appear so me to be an ISP) has many spamers are their clients.
uu.net had faced the usenet death penalty some time earlier.
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?
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.
