Thanks guys for your time.

Thats true, but I give it a try.
I think that is the easiest way to do this.
Thanks

Well do by all means, but it's very easy to do it properly.
echo -n "foobar" | md5sum | head -1c
gives you 16 subdirectories (0-9, a-f) with very good
balancing. As long as
this has been stuck into a database then you can use a DB
search whenever
you want to find which subdirectory a particular account is
in.

That`s correct, but Exim has to find the maildirs first, to deliver the
mails.
I tried Dovecot Imapd and found that it can handle variables like "%1u"
which returns the first letter of the username.
In the Exim config I can use the function "substr" to get the same
results. Now I can combine these to take the first and the second
letter from the username (or even more) to get a better balance.
With this I can build a directory structure like this (for the user
totty): "/var/spool/mail/t/o/totty".
Is there a possibility to use this within Courier (like the variables
from Dovecot or the "substr" from Exim?
I haven`t found any hints in the documentation on the website.
Is there any other documentation?
Thanks

You will need to write your own authpipe module.

Yes, so you have two simple options:
(1) Make Exim perform the same database lookup as you've
configured
courier-authlib to do;
or
(2) Make Exim send a query directly to courier-authlib's
authdaemond to map
a username to a home directory.
See for example
http://ws.edu.isoc.org/workshops/2005/
pre-SANOG-VI/bc/mail/configure.authd
and search down until you reach the
"authdaemon_lookup" router.

That are really good ideas, thanks.
So many roads lead to Rome.
Thanks to all for your time.
