I haven’t tried anything yet as I am trying to learn before I do anything (and trial and error is a very slow method), but it seems to me that just that line cannot be enough. Because how does “ldap:” know to go looking in the LDAP structure at "/Users/<username>/“ in the LDAP “/LDAPv3/127.0.0.1”? Somehow I shall have to tell dovecot that.

But if trial and error is the only way, I’ll have to try.
