Not being able to send email from spree 3, rails 4

Question

I'm having hard time configuring smtp with a rails app. I have done it many times in the past without spree which worked fine. But for some reason, Im not able to get my smtp settings work with spree to send emails.

Here is my configuration:

  config.assets.raise_runtime_errors = true
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
    address:              'smtp.gmail.com',
    port:                 465, # Doesn't work with 587 either 
    domain:               'gmail.com',
    user_name:            'email@gmail.com',
    password:             'emailPassword', 
    authentication:       :plain, # Tried :login too
    enable_starttls_auto: true
   }

I get a couple of errors listed below Net::ReadTimeout: Net::ReadTimeout and Net::OpenTimeout: execution expired

Below is the stack trace

Net::OpenTimeout: execution expired

I've tried setting up mandrill thinking that gmail might have been blocking my emails but that didnt work either.

Note: I want to be able to configure SMTP with spree3 and I'm not using spree_mail_settings gem. For some reasons spree_mail_settings didnt work for me.

Any help will be highly appreciated.

Edit 1: I know my smtp config is fine but may be I must set some spree related config vars that would let spree use the new config just like in previous versions of spree. I have explored the docs and did not find any help.

Thanks in advance.

A temporary fix can be disabling IPv6. Add following lines to /etc/sysctl.conf:

#disable ipv6
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1

Then from terminal, you can confirm IPv6 (0 means enabled & 1 means disabled):

cat /proc/sys/net/ipv6/conf/all/disable_ipv6
