Hi all I have Mozilla 1.5 and use Mozilla Mail for viewing newsgroups. How do I cleanup old threads/topics ie. the ones that are no longer on the server but still appear in the Mozilla mail window? In the Mail and Newsgroup settings I have found an option that states "When it is time to clean up messages: Keep messages which have arrived within the past xx days". I figure there must be some way to do the cleanup but how? Thanks in advance miskairal
