Mail directory structure

Hello,

I’m looking to set up my mailboxes so that they have the following structure, would anyone be able to point me in the right direction please. Thanks.

Assuming I have 3 email addresses for 2 domains: tom@example.com, dick@example.com and harry@anothersite.com I would like the mail to be in the following directories:

tom@example.com:
/home/user-data/mail/mailboxes/example.com/tom/

dick@example.com:
/home/user-data/mail/mailboxes/example.com/dick/

harry@anothersite.com:
/home/user-data/mail/mailboxes/anothersite.com/harry/

Sorry but Mail-In-A-Box does not support modifications like these. (I am not sure how to do it either way, I am sure someone here can help you)
