Disabling SMTP-Auth in Netscape Communicator
The Messenger mail client included in Netscape Communicator has a known bug related to SMTP authentication. Though SMTP authentication works with Netscape Messenger, versions 4.0 through 4.8 fail to save the password. This document is intended to assist in disabling SMTP authentication in Netscape 4.0 through 4.8 inclusive
- Open Netscape
- Open the Edit menu and select "Preferences."
- Open the "Mail & Newsgroups" category, and select the "Mail Servers" subcategory
- In the section labeled "Use Secure Socket Layer (SSL) or TLS for outgoing messages" select "Never."
- Click "OK" and close Netscape.
Locate the "prefs.js" file for your profile. This will be located in your individual profile's folder. For example, on a Windows98 machine, the prefs.js file for a profile named "joe" will be located at "C:\Program Files\Netscape\Users\joe"
-
Open the "prefs.js" file with your favorite text editor. This may be "notepad" on Windows, or "simpletext" for Macintosh.
Add the following line to the bottom of the existing text:
user_pref("mail.auth_login", false);
Save the file, and you are finished. Netscape will no longer attempt SMTP authentication.
Caution: manually editing the preferences files for applications can lead to unforseen consequences. Please back up any important information handled by Netscape Communicator before attempting this.
