Gitlab setup not sending email - email

Question

I am trying to setup GitLab in windows azure. I followed this blog Setup GitLab in azure and it is working as charm. But I could not configure smtp mail sending through GitLab.
I have followed this settings SMTP Setup. Tried both Gmail and Zoho, with both ports 465 and 587
I am getting the following error
2016-09-21_09:44:28.55626 2016-09-21T09:44:28.556Z 13562 TID-vskyw WARN: {"class":"ActiveJob::QueueAdapters::SidekiqAdapter::JobWrapper","wrapped":"ActionMailer::DeliveryJob","queue":"mailers","args":[{"job_class":"ActionMailer::DeliveryJob","job_id":"6a954ac7-19d6-4b27-b28c-c511f25e6896","queue_name":"mailers","arguments":["DeviseMailer","confirmation_instructions","deliver_now",{"_aj_globalid":"gid://gitlab/User/1"},"tgShkQTx5e1sALoxkkGi",{"to":"<my email here>","_aj_symbol_keys":["to"]}],"locale":"en"}],"retry":true,"jid":"cbd7dc87ce4202265d1a6be7","created_at":1474450319.7324607,"enqueued_at":1474451065.2083879,"error_message":"end of file reached","error_class":"EOFError","failed_at":1474450320.9358478,"retry_count":5,"retried_at":1474451068.5555682}

I tried various combinations for SSL and TLS, but no luck yet!
I am using GitLab 8.11.7
Any help would be appreciated.
UPDATE:
I tried with GMail smtp and it works fine after allowing access to apps using this URL. This issue might be due to some Zoho's smtp policy

You should use the new smtp configurations
If you're installing from source and use SMTP to deliver mail, you will need to add the following line to config/initializers/smtp_settings.rb:
ActionMailer::Base.delivery_method = :smtp
As seen in https://gitlab.com/gitlab-org/gitlab-ce/blob/master/doc/update/8.10-to-8.11.md#smtp-configuration
A configuration exemple for smtp_settings.rb is:
if Rails.env.production?
Rails.application.config.action_mailer.delivery_method = :smtp
ActionMailer::Base.delivery_method = :smtp
ActionMailer::Base.smtp_settings = {
address: "email.server.com",
port: 465,
user_name: "smtp",
password: "123456",
domain: "gitlab.company.com",
authentication: :login,
enable_starttls_auto: true,
openssl_verify_mode: 'peer' # See ActionMailer documentation for other possible options
}
end
You can see the sample file doc for configuring SMTP at https://gitlab.com/gitlab-org/gitlab-ce/blob/8-12-stable/config/initializers/smtp_settings.rb.sample#L13?
You can see more configuration options here http://api.rubyonrails.org/classes/ActionMailer/Base.html#class-ActionMailer::Base-label-Configuration+options
