The delivered addresses are listed in a tree format. Check out the
paragraph that starts "Following the options are those addresses to
which the message is not to be delivered." Note the "not".
1. Using "exim -bp" as input might be easier - that copes with split
spools automatically for you, and lists only undelivered addresses.
2. Just in case you were thinking of modifying the spool files (though
you imply not):
While is is highly unlikely that I'll ever change the format of spool
files incompatibly, it would definitely be safer to use the command
"exim -Mad" to do this job rather than trying to manipulate the spool
files yourself. (Note: if you do modify a spool file, you will need to
lock the message by locking the -D file. Otherwise Exim may be working
on it at the same time as you are. Also, the way Exim updates -H files
is to rewrite a new file and rename.)
