Anti-Spam

[Carles Latorre]

Hi everybody,   I've installed qmail in a Red Hat 5.1 and I've been noticed that my server is used for spamming purposes.   I've tried something in hosts.allow, putting parameters like   tcp-env: xxx.xxx.xxx.xxx : setenv = RELAYCLIENT   where xxx.xxx.xxx.xxx is the IP or IP range granted to send messages through my SMTP server, but it seems not to work properly.   Can anybody help me?   Thanks in advance,   Carles Latorre i Musoll Tècnic de Sistemes STRATEGY Consultors   C/ Casp, 106 1er 1ª           Pº de la Castellana, 141 08010 Barcelona               Edificio Cuzco IV Tel:   93 232 73 73            28046 Madrid Fax:  93 231 56 56            Tel: 91 749 80 32                                        Fax: 91 570 71 99   [EMAIL PROTECTED] http://www.strategyconsultors.com
