hello, i've a little problem with the smtp authentication.
if a user try to send a mail without authentication mode it work!
Can i force to use only the auth mode ??
if i telnet on the port 25 i have this result
250- -=NO UNSOLICITED BULK E-MAIL=- 250-PIPELINING 250-8BITMIME 250-SIZE 0 250 AUTH LOGIN PLAIN
