Addressless SPAM

[a4pacific]

I recieved a few porn spam which were not even addressed to me. They were addresses to "NTL User".

I am curious to know how did they get into my mail box, and will NTL attempt to eliminate this sort of spam.

My guess is they were probably trying random names with @ntlworld.com at the end, so they knew you would be an NTL user!

NTL will not do anything about them unless they came from another NTL user.

My solution is to use Mailwasher, and set a filter to delete and bounce any mail which is addressed to "NTL User".

I know this subject has been thrashed to death elsewhere but what is particulally alarming is spam that has no sending address at all, how is it that such mail:

1. gets onto the net?
2. gets transmitted?

I know most spammers use fake addresses but spam which seems to have no address at all how on earth does it work. My Mailwasher programme finds this a problem and only filter it out.

Any ideas out there?

Try this at home ... but change the imaspammer bit to your own e-mail address



telnet smtp.ntlworld.com 25
HELO imaspasmmer.com
MAIL FROM: imaspammer@ntlworld.com
RCPT TO: imaspammer@ntlworld.com
DATA
From: Bill Gates <bigbillg@microsoft.com>
To: Milinda Gates <dabossesmissues@microsoft.com>
Subject: Cheep Viagra
I think we ought to buy some!

All the mail server cares about is the helo, which could be just about anything.

The MAIL FROM, must be a valid domain name.

The RCPT TO must be a user on ntl's network.

Otherwise anything else is handled by your own e-mail client.
