It's not complaining about base_dir's permissions, but auth-userdb
socket's permissions. See:

service auth {
  # auth_socket_path points to this userdb socket by default. It's typically
  # used by dovecot-lda, doveadm, possibly imap process, etc. Its default
  # permissions make it readable only by root, but you may need to relax these
  # permissions. Users that have access to this socket are able to get a list
  # of all usernames and get results of everyone's userdb lookups.
  unix_listener auth-userdb {
    #mode = 0600
    #user = 
    #group = 
  }

Maybe you want to set "user = vmail" or something.
