Hello world ! How to allow SMTP/POP traffic bypassing squid,what is the iptables configuration for it,my proxy is working fine (transparent mode) except mail clients such as MS Outlook and Outlook Express.Please help me out,our mail clients are not working since last 3 days!! I have configured squid 2.6 (squid-2.6.STABLE4-1.fc6) on fedora core 6 , squid is running normally and I am getting Internet access all over the network via this proxy,but it is blocking all the mail traffic as all the mail clients on windows machine are not working ,webmails are working fine,I can not ping any website from the windows command prompt but getting full internet access in the browsers,can anyone tell me how to configure the squid parameters to allow the mail traffic, what ports shall be opened.I have set http_port 3128 transparent.Please tell me how to configure squid 2.6. Thank you. Regards Rahul Tidke
