Kmail devs can glue kmail to an unrelated suite of crap which pops up rss feed
notifications which can only be disabled by tracking down and deleting unwanted
commands out of the /usr/bin directory so it _can't_ run the notification.
Kmail has been decomposing for years.
As for performance, my email mbox goes back to 2004, and has 19k messages in
it. The linux-kernel mbox file keeps dying (corrupting its index) when it
passes 100k messages and I have to split it.
No, my beef with kmail is that the editor goes into weird states inserting
text into the middle of messages, to where it's adding about one character
every two seconds and I can type two lines ahead and then go get a drink and
come back before it's caught up.
The _new_ kmail version (the one xubuntu 9.04 gave me, anyway) takes about 30
seconds to pop up the busybox mbox file in "threaded" view. That's only got
20k messages in it. (And don't get me started on how unpleasant and non-
obvious they made it to actually _select_ threaded view in the new version.)
I've been looking to replace kmail for a couple years now, it's just the
alternatives suck worse.
Kmail is a bad example, unless you were _looking_ for a pathological case...
