pop3 access vis squid ? or alternate

sunlinux · 09-28-2006, 01:39 AM

Hello,

I have installed Redhat AS with squid proxy server. My clients PC are windows XP & others. Clients have Outlook Express as email client & downloads emails from mail server which is located on Internet. If I configure clients PCs to access internet via Squid proxy server than it works well. But iOutlook Express can not connect to mail server. I have enable respective ports on Squid proxy server but still Outlook Express can not connect to mail server. What do I have to do to configure this so that email also works via proxy.

Regards...

squid is not a pop3 proxy so any mail client will not be able to connect to the mail server via squid!

as actually stated on www.squid-cache.org

Squid supports...

* proxying and caching of HTTP, FTP, and other URLs
* proxying for SSL
* cache hierarchies
* ICP, HTCP, CARP, Cache Digests
* transparent caching
* WCCP (Squid v2.3 and above)
* extensive access controls
* HTTP server acceleration
* SNMP
* caching of DNS lookups

Yes Nathanael is right Squid is not a Mail proxy but i have another alternative ie Try to make ur linux pc a gateway server by "IP Masq." or IP Tables. It is just like in some cases you have also seen this in windows envoirnment that suppose u have a proxy sever install on one windows machine and you are accessing the internet connection on client machine efficiently via windows proxy machine but u are not able to get mails on client pc via outlook or on some other mail clients. but when u switch over ur windows proxy machine to ICS(Internet Connection Sharing) or make that machine gateway u are starting accessing mail on ur client machine. So same principle will work on linux envoirnment.

that aint a proxy either!

anyway - it does not really make sense to have a proxy for 2 pop3 clients! it makes more sense to have a proxy for an internal mail server!

an http proxy for example will cache so that the next client with the same request will get the cached result served rather than sending out a new request to the main web server thus speed is enhanced.

now a pop3 proxy (or imap proxy) will rather 'cache' the connection to the server - thus overhead speed is enhanced as the clients dont have to open new connections each time they want to fetch mail or do something else!

if you have 2 maybe 5 clients that still aint going to be worth it! start with 50 to a few hundred clients...
