I second this request, my school's server must restart or something every day at 4:00am and I have my mail set to check often so every day it gives me that error message saying it can't connect to the server. It also asks for my password at random times, can't seem to remember it other times, doesn't work too well with IMAP settings and a few other problems with attachments. Well I think that's it for now, I would love to know when apple is planning on updating Mail, b/c it really needs it.
