Today I have configured Squid proxy in my office. it is working fine with out any issue. But from that time, my colleagues are unable to send/receive the emails through Microsoft Outlook (2003 & 2007). But they are able to send the mails using Internet explorer ... Please let me know the sollution to allow the outlook emails through squid proxy.

Squid doesn't proxy SMTP/IMAP/POP/LDAP or whatever else your email clients are using - it supports HTTP, HTTPS, FTP, and gopher.

When you installed the squid server, how did you configure the clients to use it?

  • In Internet Explorer : Tools --> Internet options ---> Connections ---> Lan settings ----> Use a configured proxy server Mozilla ---> Edit ---> Preferences ---> Connections ---> Ipaddress of proxy server Chrome and so on – Gopi Krishna Mar 04 '10 at 18:41
  • If that's the only change you made to your networking, then squid shouldn't affect anything. – quadruplebucky Mar 04 '10 at 21:09
  • I know that squid won't proxy smtp/imap/pop/ldap but... How should we handle this problem, then? Nat? Port forwarding? I have a single NIC on my squid server and I'm clueless :( – Pitto Jan 20 '12 at 08:33
  • For the record, it is possible to get squid to proxy SMTP, but this is disabled by default. It is also a very bad idea to set it up so it is possible since it can be used very easily to send out spam. – Zoredache Feb 29 '12 at 21:07

I would suggest you take a look at the proxy's firewall settings if it's directly in the way of network traffic entering/exiting the network.
