mail_location hashing & lowercasing?
Currently, I'm using mail_location = mdbox:/var/spool/mail/%Ld/%Ln/mdbox
Now I want to add a partitioning (so I don'T have all directories in one single directory), but can't find the right syntax:
mail_location = mdbox:/var/spool/mail/%Ld/<HASHING HERE>/%Ln/mdbox
It seems like I'd need to use %N (new hash) on %Ln and then take a substring of that.
%2NLn
2 Characters of the %N hash of %Ln (the lowercase username)
But this gives me a verbatim "Ln" on the path!

Hm.
I have home=/srv/mail/%2NLn/%2.16NLn/%Ln/ in my auth-ldap.conf.ext and this gives me a path like this: /srv/mail/0/08/myusername
I use version 2.2.13 of dovecot.
Beware: %2NLn does not give you two characters, it just gives you the values 0 and 1, because it means "mod(2,new_hash(lowercase(username)))"
If you want the first 2 characters, you need %256NLn, or better %2.256NLn, see the section about modifiers in http://wiki2.dovecot.org/Variables

%N could be a 2.2 feature. Someone with besser memory of version changes will have to clarify this.

%N requires a 2.2.3+ Dovecot.
But %H will do the trick for previous versions. BUT %H will give a bad distribution if your %n ends in the same characters ex. username@your.domain. This can be rectified by reversing the string using %R.
Have not tried this but could %2.256HRLu do the trick? Have fun
