Well, AOL doesn't seem to be losing customers at a very high rate doing the same thing. All outbound port 25 traffic on AOL gets diverted to internal mail servers. This may not be fully implemented yet, but where it is it works great. Even stamps an X-Apparently-From in there with the real AOL "Screen Name". Since doing this AOL Spammers have gone to a near 0 level. Last I read, UU.Net is starting to force all their dialup resellers to use a filter or diversion on port 25 too. Except the rare telecommuter (Who in all reality should be using a business account anyways, as there is no price difference, just one is taxable and goes into a different group), I don't see there being a real reason a residential dialup account needs to use a non-local mail server, IF you trust local users to specify domains. If you don't, all bets are off. As has been said several times, there is no 1 thing that works for everyone. It takes a combination of things to work. Port 25 diverting is just one tool in the proverbial belt. -- Jason Slagle - CCNP - CCDP Network Administrator - Toledo Internet Access - Toledo Ohio - [email protected] - [email protected] - WHOIS JS10172 /"\ . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . \ / ASCII Ribbon Campaign .
