If you have something like mailAddress=user in your pass_attrs and user_attrs, so that the username gets translated to the mailaddress then you can use %n/%d in dovecot.conf.

The correct syntax is:

user_attrs = =home=mail:/srv/mail/%d/%n, ..

but this assumes that the login is user at domain.

Without changing the username to mail address you can't use %d/%n directly, and post-login script would be the only way to go.
