How do I get a telnet localhost 25 output of 250-AUTH LOGIN? Similar to the questions asked here and here, I set up a Postfix-Dovecot mail server using Ubuntu 12.04LTS and can not get it to authenticate.

When smtp_tls_auth_only = no (as recommended here), my connection closes:

Trying ::1...

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

Connection closed by foreign host.

When smtp_tls_auth_only = yes, here's what I get:

Trying ::1...

Trying 127.0.0.1...

Connected to localhost.

Escape character is '^]'.

220 mydomain.com ESMTP Postfix (Ubuntu)

ehlo localhost

250-mydomain.com

250-PIPELINING

250-SIZE 10240000

250-VRFY

250-ETRN

250-STARTTLS

250-ENHANCEDSTATUSCODES

250-8BITMIME

250 DSN

Note that depending on how I set the alias_maps flag e.g. from the default hash:/etc/postix to the optional (see www.postfix.org/pgsql_table.5.html) alias_maps = pgsql:/etc/pgsql-aliases.cf, I get different output but still cannot get past some of the consistent failures related to private/auth or /var/spool/postfix/private/auth.
