Problem with webmail solutions using squid

["Zoltan Sutto" <sutto.zoltan@xxxxxxxxxx>]

Hi!

We have problems with various free webmail solutions using 
squid-2.5.STABLE14-3 as a non-transparent proxy.
  httpd_accel_uses_host_header off

I tried using no_cache and always_direct  directives with the correct acls 
on these sites with no success.
There isn't any port forwarding rules for transparent proxying also.

When I remove the proxy server from IE Connection settings the webmail 
solutions works correctly. Every page displays correctly.

Any help would be appreciated.

Thx
Zoltan
