Click below and see how many hundred links you get

http://www.google.com/search?q=setting+up+linux+server+isp 

Also see http://www.local.net/~jgo for setting up assorted services 
on Linux.  Fantastic - right from the basics to the really advanced 
stuff.

Finally, as a new ISP, consider setting up a strict AUP (Acceptable 
Use Policy) to discourage spammers, and make sure that your users 
who spam will forfeit their accounts.  See the AUPs of major isps in 
the states and model yours on these documents (see 
http://www.psi.net or http://www.digex.net for example)

Check that your servers are not open relays (see 
http://www.abuse.net/relay.html for pointers - there are 17 hacks to 
relay mail through a server).  Usually, properly configured sendmail 
8.9.3 (or the latest 8.10.x beta) should do the trick.  Don't install 
any sendmail lower than 8.9.2 (or try qmail instead).

Subscribe to the MAPS RBL and DUL to block spam at the router 
level.  See http://maps.vix.com/rbl and http://maps.vix.com/dul for 
more info.  The RBL blocks mail from sites which persistently host 
spammers / relay spam, and the DUL blocks mail originating from 
dialups.  

[Reason for the DUL] All legit mail should originate from a MX 
server, not directly from the dialup.  Mail originating from a dialup 
usually means that the spammer is running an smtp server on his 
desktop to relay spam  (direct to mx spamming)

Also see http://spam.abuse.net	 and http://www.cauce.org - 
consider joining CAUCE as an organizational member to promote 
anti spam measures and support the crusade against spamming.
