John, Suggest every SOHO running own mail servers out of dynamic address range to configure the associated ISP SMTP server as a nexthop/smarthost/relay/default-path as discussed here before. On a short to medium term addresses listed on dynablock.easynet.nl (see http://informatie.easynet.nl/error/errors.html#dynablock for an in-depth information) should not be able to contact the outside world by SMTP, even if no ISP likes this idea - because it will create to much unnecessary helpdesk activities.
For the moment blocking of IP ranges as - for example - policy listed on dynablock.easynet.nl - is one of the effective solutions to avoid being hit by M$ systems running wild, and certain ubiquitous spammers not listed (yet!) on the dynamically managed lists. Hope your ISP has a reliable SMTP server for outgoing mails readily available. And of course I don't like the idea the ISP are implementing those lists for their customers incoming mails - control must remain under the users or users organization. This might be hard for us hardcore security people - but it's reasonable. -Kurt. PS. Yep, I had the impression to be locked out from John's security list and had not checked the very long list of blocked items before ...so this thread came in here - IMHO perfectly on topic. Thanks for the phone call btw. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of John Morgan Salomon Sent: Wednesday, November 12, 2003 12:14 PM To: [EMAIL PROTECTED] Subject: [swinog] Easynet dynablock Hi guys, this isn't a troll, and I forgive me if it's slightly offtopic, but I was wondering what people think of dynablock.easynet.nl? <snip> ---------------------------------------------- [EMAIL PROTECTED] Maillist-Archive: http://www.mail-archive.com/swinog%40swinog.ch/
