I am using Ruby MRI 2.0.0 and Rails 3.2.12 on a Ubuntu 12.04 TLS VPS and attempting to setup email notifications in my app. It was working fine a few days ago, but not anymore. My web host is OVH.
My SMTP settings:
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
ActionMailer::Base.smtp_settings = {
:address => "smtp.gmail.com",
:port => 587,
:user_name => 'sender@gmail.com',
:password => 'secret',
:authentication => 'plain',
:enable_starttls_auto => true
}
Using RAILS_ENV=production rails console:
class MyMailer < ActionMailer::Base
def test_email
sender = "sender@gmail.com"
receiver = "receiver@example.com"
mail from: sender, to: receiver, subject: "Hello!", body: "World!!"
end
end
=> nil
MyMailer.test_email.deliver
The output:
Net::OpenTimeout: execution expired

I tried the following:
- The
exception_notificationgem was added to the setup a few days ago. I tried to comment its line inGemfileas well as its matching configuration, and runbundle install. After restarting the server, the issue is still present, even if I delete and recreate the gemset. - Test it out on a virtual machine (exact same setup as the VPS including iptables rules): works
- Disable iptables rules: does not work
- openssl を使用して VPS から手動で Gmail に接続します:動作します(したがって、これはファイアウォールの問題ではありません - ここを参照してください:コマンドライン経由で smtp.gmail.com に接続する)。
- Gmail アカウント オプションで IMAP を有効にする (無効になっていました):動作しません
- 別の Gmail アカウントを使用する:機能しません
- Ruby 2.0.0 を Ruby 1.9.3 に置き換えます
- Rails 3.2.13 へのアップグレード
誰かがこの問題を解決する方法について手がかりを持っていますか?
ありがとう！
