I guess NO because communication is via socket.

My exim-4.72 configuration (which doesn't use LOGIN) contains:

| plain:
|   driver = dovecot
|   public_name = PLAIN
|   server_socket = /var/run/dovecot/auth-client
|   server_set_id = $auth1


And the dovecot-1.2.12 configuration contains:

| auth default {
|   mechanisms = plain login
| 
|   passdb pam {    
|          args = dovecot
|   }
| 
|   socket listen {
|     client {
|       # The client socket is generally safe to export to everyone. Typical use
|       # is to export it to your SMTP server so it can do SMTP AUTH lookups
|       # using it.
|       path = /var/run/dovecot/auth-client
|       mode = 0666
|     }
|   }
| }


Hope it helps. YMMV.
