Disabling the WebMail look&feel

Hi

I’m using the inotes60.ntf template in a iNotes (webmail) server.

If some user has an outdated or unsupported browser, he won’t be able to access to the iNotes look&feel, but he will be presented with two alternatives: Use WebMail or Logout.

How can I do to disable this behavior ?, I mean, just giving this user the choice to logout from this server.

Thanks for any suggestion.

J. Carminati.
