I use the approach characterized by this statement I > found at a spam elimination site on the web: That is great for home mail machines, but it generally hasn't worked for me for business setups. Half of the small businesses in the area have Verizon "business class" DSL, and want to run ther own MTA's. The Verizon netblocks inevitably end up on somebody's blacklists, and then the small businesses can't email each other, and I have to spend fifteen minutes routing their mail through somewhere else until they complain to Verizon about the RBL listing and get it delisted. And they seem to think that they shouldbe handling their mail on their own, rather than sending it through Verizon's outgoing MTA. Similarly with my Debian mail - I get almost no legitmate email from anywhere in Asia or Africa, and very little from Europe. I would love to just drop them at the border, but people have this habit of trying to email a maintainer directly, and I sort of feel like I can't just toss out the baby with the bathwater. I wish I lived in a world where I could make those decisions, though - it would mean I don't have to replace my aging MX any time soon :) -- -------------------------------------------------------------------------- | Stephen Gran | It's there as a sop to former Ada | | steve@lobefin.net | programmers. :-) -- Larry Wall | | http://www.lobefin.net/~steve | regarding 10_000_000 in <11556@jpl- | | | devvax.JPL.NASA.GOV> | -------------------------------------------------------------------------- Attachment:
