I have configured my router (192.168.1.2) to serve only one machine with IP 192.168.1.6 and set up a SQUID proxy on 192.168.1.6. I have defined some rules (ACL) regarding connections to internet on SQUID proxy.
I changed the Gateway of the rest of the machines (192.168.1.60 - 192.168.1.69) from 192.168.1.2 to 192.168.1.6.
The policies which I defined in SQUID are working properly but 'Linux Evolution mail' client is not fetching mails.
Do I have to change any other settings on 'Linux System' or 'Evolution mail client'?
