sarky Posted April 9, 2006 Share Posted April 9, 2006 Hi All, After doing a lot of research for Yonks and i have not seen a post which actually answers my question. I am an ISP with a /24 Address, in a country that is known to be SPAMAHOLIC , i am taking a satellite feed to serve my customer base with over 600 Clients. I have stuck up a firewall and i keep updating with ports that the latest Viruses are using so the unaware will not be able to harm or replicate on the Wide net. Proxy and Natting is something which is widely used on my side and definitely on a lot of other networks around the World. I am going to secure my Mailserver to make sure that it is not used to send spam out of it but i am still researching on the software to use Any points here will be well apreciated for mailserver <Sendmail> I keep receiving Email about IPa or IPb sending spam with the header files attached, after checking it out, all spam generating from my system is sent through FREE WEBMAIL, where a kid of 6 can have an email address. If my network is being used to access a http site and do the crime HOW can i or other admins out there be able to track those http queries. One solution i heard a couple of years ago from the IP Source (Main Feed), Said block all access to FREE MAIL <Funny One Mind>. The above solution is a dire solution and in if i end up blocking half of the list or the main ones, i would loose customers and i might as well close up shop. Major clients are cybercafe's and they know the fight we are going through but still it is not something which can lead to a 100% eradication. I would like to hear other admins out there on points about tackling this above issue. Thank you all Sarky Link to comment Share on other sites More sharing options...
