Well, if you are using a local SMTP or sendamil(postfix) many servers adopted a brain-dead "solution" to SPAM called DULs (for Dial Up Lists, but probably indicative of the quality of thinking that went into the strategy, too). What this means is that they won't relay mail from machines whose IP matches inside one of the DULs. Some servers include all DHCP-assigned addresses as well as Dial-Ups. This may be what your friend is encountering--nothing to do with his iptables. As far as stopping SPAM, DULs are a totally whacked strategy. A single machine with a static IP(may not even have to be static) and rawsockets can be any IP it wants in its mailings if set up properly, and with a little 1M connection could flood a lot of us with more SPAM than we could eat in a lifetime. These days that means a box with XP home edition and a script kiddie hired by a spammer But then the internet was ceveloped for scientists to exchange data, not to cure stupidity. Civileme
