mail_location=maildir:/buzones/us.es/%1Hu/%2.1u/%n but I get the following directory tree:

Numbers with %H work in a special way (actually I had completely forgotten about this):

%H - take a 32bit hash of the variable and return it as hex. You can also limit the hash value. For example %256Hu gives values 0..ff. You might want padding also, so %2.256Hu gives 00..ff. This can be useful for example in dividing users automatically to multiple partitions.

 The ideal directory layout should be the following:

 First directory level: Letters from a to z
 Second directory level: Numbers from 0 to 200
 Third directory level: %n (username without @domain)

That's not possible, but you could have the same number of directories with: %2.26Hn/%2.200Hn/%n
