The issue is that there are ISPs that have filters such that their dialup customers cannot talk to port 25/tcp of systems elsewhere on the net. Customers have to use the provider's SMTP servers. The question is, is this a good thing? I don't think anyone would argue against UUNet and PSI doing this with the *.ms.uu.net dialups or the *.pub-isp.psi.net...but would you do this on your own network? I've blocked 4 ms.uu.net /16's and 12 pub-isp.psi.net /24's from talking directly to FDT's mail servers. Unfortunately, most of the junk from PSI is relayed through other sites anyway. ------------------------------------------------------------------ Jon Lewis <[email protected]> | Unsolicited commercial e-mail will Network Administrator | be proof-read for $199/message.
