Erratic results when using the Web Interface client through a proxy server.
Erratic results when CMail Server WebMail is used in conjunction with a proxy server on
the same Local Area Network. Examples include: only one user is visible in the WebMail
Logged In Users display panel, another users inbox, outbox or options settings page
is displayed in place of the users own etc.
All users connected to the LAN send their Internet traffic through the proxy server and
therefore appear to come from the same IP address - i.e. that of the proxy server. WebMail
relies on knowing the IP address of the client in order to check the state of the user.
This of course, is masked by the proxy server.
Under 'Proxy Exceptions' in proxy settings section of the client Web Browser
(Netscape & Internet Explorer), place an exception for the IP address of the
workstation running CMail Server followed by a colon ':' and the port number WebMail
listens to. For example 192.168.0.1:8002. The client Web Browser will
then make a direct connection to WebMail, bypassing the proxy server and reporting the
real IP address of the client.
Authentication by Cookies can also be enabled from
the Web User Interface to counter this problem but cookies can be unreliable.
