Re: [swinog] SPAM from own customers

 We're thinking about some sort of rate-limiting technique
 for postfix. But it seems not to be an easy task, if it
 must scale...

We are working on something like that

[swinog] SPAM from own customers

2003-12-02 Thread Michel Renfer
Hi All

The topic Spam sent over infected or malconfigured enduser pc's
will become an big issue. We saw Virus' sending Spam directly from
the users pc, downloading the recipient list and the payload trough
HTTP from the web.

How will you deal with the problem, that one user can flood your
SMTP Server with tousends of emails within 10-20 minutes?

Opinions, Suggestions?

thanks,
michel

ACK.

Think of a modification of our Dial-Spam-Block: 
http://dial-spam-block.sourceforge.net/
http://www.init7.net/anti-spam/index.php

It counts the receipients and blocks automatically after for example 200.
