I use Thunderbird for newsgroup access. It has message filtering that is easy to setup but seems to have one or two problems.
If I set it up to filter one of the groups more persistent trolls and set it to delete all messages all works fine. But then I get all the replies.
If I set the option to ignore sub-thread then the whole sub-thread is hidden but the thread is not marked as read (even if I do it manually) so it continues to appear in the list of threads with unread messages.
I can set both rules but for reasons I cannot fathom it then seems toi still show the sub-thread.
Is there a set of rules that will ignore a troll, all replies to their messages AND allow the whole thread to be marked as read?
