email filtering

[David Fletcher]

I'm still using Kubuntu Hardy, because I'm extremely reluctant to move to the 
new KDE. So, I'm looking into ways to disentangle myself from dependency on 
KDE.

So, to this end, I've been moving all of my email out of kmail and onto a 
separate IMAP server, which is working very well.

Unfortunately kmail has filtering functionality which is very much to my 
liking but I can't so far duplicate with either Evolution or Thunderbird. I 
have a load of folders for mailing lists, personal etc and filters for 
shifting email into them. Unfortunately if I'm browsing the inbox at the 
time, messages tend to be marked as read before being moved, then they 
effectively vanish into a folder marked as already read before I get chance 
to see them, so I don't then know where to go for my new messages.

What kmail allows me to do is add to the filter after the message has been 
moved, another instruction to mark it as "Not Read" so it is always obvious 
where my new messages have been moved to.

Without running kmail under gnome or xfce, is there any way to do this in a 
different email client? I've seen the time delay feature in Thunderbird but 
don't like it.

Sorry the description is a bit long - hope I made myself clear.
