Yes, but it is not very helpful. 

Here is the log if I do it again right after grml2hd:

cp /etc/postfix/main.cf /etc/postfix/main.cf.org

% dpkg-reconfigure postfix
Local delivery only - You are not on a network.  Mail for local users is 

  1. No configuration  3. Internet with smarthost  5. Local only
  2. Internet Site     4. Satellite system

General type of configuration? 3


The relayhost parameter specifies the default host to send mail to when no entry
is matched in the optional transport(5) table. When no relayhost is given, mail 
is routed directly to the destination.

SMTP relay host? (blank for none) [smtphm.sympatico.ca]


Postfix is now set up with the changes above.  If you need to make changes, edit
/etc/postfix/main.cf (and others) as needed.  To view Postfix configuration
values, see postconf(1).

It doesn't touch anything on setting Postfix to relay my mails through my
ISP with SASL required, ie, all the smtp_tls_ setting are not there.
That's where I'm having difficulties at. 

please help
