Now I have a 1.2MB mail file on the local IMAP server. It contains 50-odd e-
mails which I'd like to import into KMail. I see a facility to import plain 
text emails into KMail, and I've copied the file onto this machine, but KMail 
complains that it can't find any messages.

What's the format required for text import? I suppose I could split the file 
by hand if really necessary, but it would be a labour, full of risk.

Meanwhile, until I can get IMAP working I may have to resort to POP3 
collection from my ISP, and wrestle with the problems that brings.

Does the team think there'd be much to be gained from submitting a bug report?
