Create a cyrus.header file in the ABC directory, set the ownership and 
permissions.  Something like this:

touch cyrus.header
chown cyrus:mail cyrus.header
chmod 600 cyrus.header

Then run:

reconstruct -x -f user.xxx.ABC


I should have asked at the beginning - are there any message files in (1., 
2., 3., etc) in the ABC directory?
