[Evolution] Case-sensitivity in filters

[Marcus Harrison <marcus harrisonland co uk>]

Hello everyone!

I'm usually a KDE user but sometimes log in to Ubuntu, and when I do I like to 
use Evolution as my mail-client. Now, I have a pretty comprehensive set-up for 
my few mail accounts, being heavily bias towards the one I'm posting from now. 
I have a lot of subscriptions and use filters to filter them into various 
folders.

I recently discovered that the filters are case-sensitive: I.E. that a filter 
set to filter messages going to, "marcus harrisonland co uk" wouldn't filter 
messages going to, "Marcus Harrisonland co uk". Given that E-mails are case-
insensitive, is this a wise decision? I'm not suggesting that it's never 
useful, but isn't there a way to switch it off for specific filters (such as for, 
"To:", "From:" and, "CC:" fields, or otherwise letting the user disable it for 
specific filters)?

Thanks in advance.
