I am trying to setup a postfix mail server locally only to send mails on Linux Mint 16. I was successfully able to send mails to non TLS MTA, but not to gmail. Later I found that I need to configure my Postfix to support TLS and SASL authentication methods.
I followed this tutorial from https://help.ubuntu.com/community/Postfix to set my mail server. My mail server is currently not opening a TLS connection
telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 Ganesha ESMTP Postfix (Ubuntu)
^Cquit
quit
Connection closed by foreign host.
From an other website I found out that postfix need to be built using ssl and sasl to support this. It looks like the default installation using apt-get of postfix doesn't support this . Do we need to build postfix from source to support this. ? Every tutorial except for one seems to use the default apt-get installed postfix and make the TLS and sasl work out of the box. Is there something I am doing wrong here ?

Is there a tutorial to achieve this ?
