[Dovecot] Migrating to Maildir -> path

Hello,

I'm in the process of migrating to Maildir, and I wondered what would be an acceptable path. I want to do virtual-accounts only, so $HOME/Maildir/ is not an option.

I was thinking of /some/path/username@domain.tld/Maildir/ and later perhaps /some/path/(firstletter)/username@domain.tld/Maildir/

but perhaps Maildir/ is a bit too redundant here....

Anyone who could advice ?

Many thanks,

Wouter
