Thanks very much - that seems to have been the whole problem.
After changing %Lu (the default) to %Ln everything seems to be working,
including spam being sent to ~/Maildir/.Spam.

It does seem slightly odd to me that %u stands for user + domain,
while %n stands for user without domain?
And why is %Lu the default?
Is it just for those using an SQL user database?
