You need to allow for people running there own serversYou need to allow for people running there own serversPosted May 6, 2004 10:30 UTC (Thu) by alex (subscriber, #1355)In reply to: Problem with your 'Solution' by rjw Parent article: 82% of email is spam You don't always want an ISP to process your mail. I run a mail server of my cable modem because I host several domains and mailing lists. Its cheaper to use my system at home where I have control rather than pay an ISP for stuff I can do myself.

You need to allow for people running there own servers Posted May 6, 2004 11:51 UTC (Thu) by copsewood (subscriber, #199) [Link] Unfortunately for this kind of mail system, one of the most effective means of blocking spam is to see if it comes directly from the kind of d IP address generally allocated to broadband users, by doing a PTR DNS lookup on the IP and looking for distinctive patters ( e.g. 4 numbers between . Addresses in this category are already getting into a number of DNS blacklists, and if more people get sufficiently fed up with spam to adopt this solution, legitimate mail systems hanging on this kind of connection without using a smart host are likely to become collateral damage. You would avoid this by configuring your ISPs outgoing SMTP server as your outgoing smart host, which would avoid this problem, and make better use of your limited bandwidth (only 1 copy of each list message uses your uplink).

More expensive than running it over a cable modem? Yeah, but you can afford it. And as another reply said, running SMTP over a cable modem isn't reliable anyway, since they tend to get blacklisted.
