If my ISP block port 25, I'll change ISP next day. But if it will be _configurable_ (blocked by default, but I can change setting by simple openimng web page and select checkbox) - why not. ----- Original Message ----- From: "Petri Helenius" <pete@he.iki.fi> To: "Gadi Evron" <ge@linuxbox.org> Cc: "Paul Vixie" <vixie@vix.com>; <nanog@merit.edu> Sent: Saturday, October 09, 2004 11:13 AM Subject: Re: short Botnet list and Cashing in on DoS

How about seeing some simple measures such as blocking outgoing port 25? at ISP's? Not a perfect solution, but it's a partial solution for some of the problems. Combined with other solutions we could start seeing a change.
Blocking ports one by one and filling the Internet by application level proxies (SMTP gateways for port 25) is not a road worth travelling.
