Re: [SAtalk] What Dynamic IPs rbl list?
I use dialups.visi.com and dynablock.easynet.nl. - Original Message - From: Marcio Merlone [EMAIL PROTECTED] To: SA List [EMAIL PROTECTED] Sent: Tuesday, November 11, 2003 9:30 AM Subject: [SAtalk] What Dynamic IPs rbl list? Hello! I was wondering what rbl lists you guys use to block dynamic IP ranges. I will use it on a gateway relay-only server, which makes anti-virus and anti-spam and then forwards messages to end server. It's a postfix box. The intention is to disallow any adsl, dial-up or dynamic/static address on such lines to send any mail to this server. I will have a separated smtp server for my customers... ;) I know, there are (few) legitimate servers running on xdsl sometimes, but I can white-list those.

It's a postfix box. dynablock seems to work pretty well and be pretty low FP.. There are some bugs/issues with it in SA where the trusted_networks does not get automatically set up properly, causing it to check all hops and not skip the first.. but when configured properly it works great. --- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.

The intention is to disallow any adsl, dial-up or dynamic/static address on such lines to send any mail to this server. I will have a separated smtp server for my customers... ;) Bad, bad, bad idea!!! There are many many people running home networks in dynamic space who send their mail thru their isp server. These will all get caught and trashed by your plan. You better have a VERY good explanation why you just alienated hundreds of current and potential customers when your boss asks why his long term customers cannot get thru your filters. There is spam control and there is political suicide, this is suicide.

Those will get in. I'll use those lists with postfix, not on SA. Those guys who runs a mail server on such dynablocks, if, and only if, using their isp smtp, will have no problem at all. There will not be a Received: line on headers if, using their MUA, they connect to ISP and send the message. Those legitimate servers running on dynablocks, if properly configured and not relay-open, may be white-listed. These will all get caught and trashed by your plan. No, they will be REJECTed with an explanation message. It's different.

We have sometimes 50-60% spam comming trough our servers. One day it got 80% SPAM! This overloads our servers (some old ones), our customers cannot pop their accounts from a dialup connection - imagine a 30MB MAILBOX, not maildir, popped from a 56K modem. I want to block those selling [EMAIL PROTECTED]@, asian porn, and such un-wanted material, which represents about 50% of the traffic (pure guess). There will be some spam that will then be easaly downloaded by our customers and then filtered. --- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.

I'm pretty sure he meant he was going to disallow dynamic-ip hosts to deliver mail DIRECTLY to his mailserver... ie: the ones that don't use their ISP server... In fact, given his message, I can't possibly see how you can read that to include mail that was properly relayed via the ISP server Bad, bad, bad assumption! :) --- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.

There will be some spam that will then be easaly downloaded by our customers and then filtered. Again, I feel deleting ANY mail addressed to someone else is a very bad idea and a liability for your company. What is spam to you might be a desirable message to someone else. After all, some people really do want to enlarge their private parts. Perhaps it would be better to enable user level control over the filtering and let those who want to get all the mail to be able to do so. Speaking of blocking mail I already cannot send mail to your address, its either invalid or your site is blocking email from my dynamic address (going thru my isp's mailer) --- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.

Good, good, good idea!! :) There are many many people running home networks in dynamic space who send their mail thru their isp server. Then, obviously, these people will not be affected. For, as you say, they use their ISP server as smarthost. Otherwise, they should take a medal and hang it around the guys who run dynablock.easynet.nl; for no DNSBL has been so effective in blocking spam as this dynamic block list. I kid you not when I say spam has been reduced by 90% and up! I'm loving it so much even, that this morning I added the entire dynablock zone to my DNS. BIND rose to a whopping 126 MB, though; so, maybe, for now, I will stick to querying remotely. But loving it, I do. :) - Mark --- This SF.Net email sponsored by: ApacheCon 2003, 16-19 November in Las Vegas.
