Some would argue that spam exists precisely because running a mail server is so economical. Perhaps it should be more expensive. Small ISPs and organizations can relay mail via their DSL provider's servers, just like individuals do. Larger organizations can pay for a real Internet connection.

It is actually better than that, because most ISPs now do some sort of antivirus filtering on their mail servers. Merely by updating the virus definition files on their mail servers, they immediately stop ALL of their customers from spreading the latest worms. This is why the worst Email worms (like Sobig) tend to use their own DNS and SMTP engines to bypass the configured outbound mail relay. - Pat _______________________________________________ Gossip mailing list [EMAIL PROTECTED] http://www.mail-archive.com/cgi-bin/mailman/listinfo/gossip
