Subject: Re: An end to spam through Graphnet
Can anyone elaborate a little more on the "one true" set of procedures that one should take to prevent spammers from abusing ones resources.
If you're using smail-3 then the latest beta makes prevention of illegal third party abuse quite trivial in the simplest cases (and the beta to come defaults to preventing abuse for normal configs).
The current problem that I have is valid customers who are "on the road" and want to sendmail through my SMTP server when they dial into att or netcom, before their eudora's used to point their SMTP server at me, that ain't happenin' after my spam attach so is there some work around that they can use?
Oi! I'd say "Just say NO!". This is one of the things I was thinking about for iPass (and in some ways it's already implemented in some of their custom installs by way of custom authentication their clients already had in place), but for random joe dial-up providor you're SOL. Maybe you could provide some form of authenticating SMTP proxy, but I'd hate to imagine what might have to be done to client software to enable such a capability. -- Greg A.
