[Koha] Email not being sent from koha

[Javed Sahil]

Hi everyone,

  I have configured postfix, mailutils  and gmail with my Ubuntu 16.04 to
send Email Notifications from koha 16.11.

I can send emails from command line using the following command:

echo "This is a test." | mail -s "test message" javedshoukat900 at gmail.com

emails are received on this address:  javedshoukat900 at gmail.com

but when I issue the command: ./process_message_queue.pl

following message appears:

connect to gmail.com failed (Connection timed out)
connect to gmail.com failed
connect to gmail.com failed (Connection timed out) no (more) retries!
 at ./process_message_queue.pl line 66.


any idea? plz.
