With IMAP use the "EXISTS" info:

1 LOGIN user pwd
2 SELECT "Customers.Fred Jones"
* 1 EXISTS
..
3 SELECT "Customers.Fred Firestone"
* 6 EXISTS
...
n LOGOUT


On filesystem count the number of regular files in cur and new subdirs:

cd /path-to-maildir
for dir in .Customers.*; do
 	let cnt="$(ls "$dir/new"|wc -l) + $(ls "$dir/cur"|wc -l)"
 	# or: let cnt=$(find "$dir"/{cur,new} -type f|wc -l)
 	# compare cnt with last count
 	# you could store the value into "$dir/lastcnt"
done

Bye,
