It's not hard to right-pad any short usernames before hashing. For instance, the username "bo" might hash as "bo__" and thus would end up in the directory "/export/mailboxes/b/o/_/_/bo.mbox". If you allow non-alphanumerics you'll want to translate those to something innocuous as well, or a name such as "bo.lee" will cause problems.One way to fix this issue would be to use a hashing scheme to split the amount of actual mailboxes into a subdirectory structure. You could get something like firstname.lastname@example.org would have his mailbox in /export/mailboxes/j/o/h/n/johndoe.mbox so in /export/mailboxes, in order to find the j directory, you only have about 36 directories entries or so. Although this example is not good in the case where you accept usernames with 3 or less characters.
