Installation guide

Starting with Netscape Communicator Version 4.5, the Namespace extension

to the standard IMAP protocol is used to locate the users folders on the

IMAP mail server. This feature will not work if you are using an older IMAP

server that does not support the Namespace extension to the protocol. Use the

following procedure to customize Netscape Communicator to be able to

locate a user’s Trash folder on an old IMAP server:

1. Select the Preferences option in the Edit pulldown menu and choose the

Mail and News Servers option in the Preferences window.

2. In the options displayed below this option, select the Mail Servers option.

3. Find the IMAP server in the scrolled list of servers. Select it and choose

the Edit button to edit the server conﬁguration.

4. In the pop-up dialog box that is displayed, choose the Advanced tab.

5. Ensure that the Namespace ﬁeld in the tab reads (quotes and period

included) as follows:

Namespace: "INBOX."

6. Click on the OK button in the pop-up window and again in the

Preferences window to save the settings.

7. Exit and restart Communicator.

You should be able to move messages to the Trash folder and all the Delete

options should now be sensitive (dark letters). Because IMAP mail server

conﬁgurations differ (including the location of the user’s folders on the

server), check with your IMAP mail server administrator if the above

procedure fails to resolve the problem.

4.1.9.6 Communicator Returns sh: /usr/bin/X11/showps: not found

When you select a link to a PostScript ﬁle in the Navigator component of

Communicator, it might return the following error:

sh: /usr/bin/X11/showps: not found

The showps helper application has been retired from Tru64 UNIX as a

result of licensing changes to Adobe Display PostScript. The user may have

customized the PostScript Document MIME type to use the showps helper

application in $HOME/.mailcap and $HOME/.mime.types ﬁles.

To resolve this problem, you must obtain a new PostScript viewer and

reconﬁgure the helper application for the PostScript Document MIME type in

Communicator. Use the Edit option in the Edit-Preferences-Navigator-

Applications pulldown menu of Communicator to edit your PostScript

Document helper application and replace /usr/bin/X11/showps with

the path to your new PostScript viewer.
