Of course you should define to which hosts you advertise SMTP AUTH.
And within your ACLs you should allow AUTH only for SSL/TLS connections.

For example:

| hostlist   relay_hosts    = 127.0.0.0/8 : 192.168.28.0/24
| auth_advertise_hosts      = !+relay_hosts
| ..
| acl_smtp_auth     = check_auth
| acl_smtp_connect  = check_connect
| ..
| check_auth:
|   accept  hosts = +relay_hosts
|   accept  encrypted = *
|   deny    message = SSL/TLS encryption required for SMTP AUTH
| 
| check_connect:
|   warn    hosts = +relay_hosts
|           control = allow_auth_unadvertised
