Any idea how to avoid this kind > of spammers ? As far as I am concerned any server should enforce password / logon to its smtp and make it a combo smtp / pop mailsend operation. That should in all likelyhood keep spammers away. Obviously it cannot cope with remote dialing in and sending via a server far away like those run by www.myrealbox.com. On the other hands as ISP its easy as if the spammer is local you have his phonenumber he used to dialin so even if the name is fake, there shouldnt be any problem catching him. We caught ourselves an internet cafe here which had decided to cut costs and use other peoples accounts to dial in. Every time his phone gets logged....He was stupid enough to try it on a friends account so we know who it is and where. Biggest problem will be to have the Thais admit they got one of those nonexisting internet problems and take action. Anyway, if they donot, the guy will likely not enjoy his stays on the internet... To run an internet cafe he needs to be on line and he has all those visitors with access to his systems(g). -- Best regards, tracer Using theBAT 1.44 mail to : [EMAIL PROTECTED] using FireTalk: 321338 LOCAL phone: 271194 -- -------------------------------------------------------------- View the TBBETA archive at http://tbbeta.thebat.dutaint.com To send a message to the list moderation team double-click HERE: <mailto:[EMAIL PROTECTED]> To Unsubscribe from TBBETA, double-click HERE: <mailto:[EMAIL PROTECTED]> --------------------------------------------------------------
