Mozilla Mailnews FAQ

Last updated on November 3, 2004.

How do I prevent messages with the same subjects, without leading Re:'s, from being threaded together?

Add the following lines to your prefs.js or user.js file:
user_pref("mail.thread_without_re", false);

Or you can enter about:config in the location bar.
Search for the preference mail.thread_without_re.
Modify the value to false.

Note: newsgroup.MSF files need to be deleted (and then recreated) for the change to take place.
