Postfix dovecot SASL smtp auth

I configured my email server following the tutorial https://help.ubuntu.com/community/PostfixDovecotSASL

Now when I telnet myserver.com 25 ehlo localhost

the output is

250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-AUTH PLAIN LOGIN 250-AUTH=PLAIN LOGIN 250-ENHANCEDSTATUSCODES 250-8BITMIME 250 DSN

===== According tutorial ,"250-AUTH PLAIN LOGIN ,50-AUTH=PLAIN LOGIN" lines mean I config myserver right . But I still sent the email without auth login .

It is weird .

Solution

  • Just like ekini says, look in your main.cf configuration file and see if mynetworks parameter is set to localhost (or 127.0.0.0/8 for instance), which is usually the case when this happens. 

     mynetworks = 127.0.0.0/8

    Also this shuld be set to yes:

    smtpd_sasl_auth_enable = yes

    Try connecting from somewhere else instead...
