How to configure squid proxy for allowing mail clients to use POP3 or IMAP


I am unable to allow mail clients like (MS Office Outlook, Outlook Express or Thunderbird) to access email through POP3 or IMAP protocol in my office. My squid proxy is configured as transparent proxy. The mail server is present at public domain and in my office public domain is accessible through only proxy.
I have tried with allowing ports 110(pop3), 25(smtp) and 143(IMAP) by creating separate access lists in proxy config file. Still it doesn't work.

Could any body guide/help me out in this regard.

Thanks in advance,

B P Sarangi,
Kolkata

This has been asked (and answered) here, and on numerous other sites, many, MANY times. Since you found this site via Google, did you try to look this up, or search here???

Squid is an HTTP proxy. HTTP is NOT pop3, smtp, or imap. This means that Squid has NO IDEA what to do with them, nor will it ever. Since it only deals with web traffic, how you configure your DMZ/router/firewall is up to you. If you want to open those ports directly, that's your call...you can also use iptables to redirect things, setting up a transparent proxy. Did you try to look at the Squid documentation???

http://wiki.squid-cache.org/ConfigEx...lesPolicyRoute
http://www.tuxradar.com/answers/432
http://serverfault.com/questions/382...-through-proxy

...are just some of the things you could easily find.
