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.
