连接被拒绝 – 连接（2）Ruby on Rails邮件设置
我在config/environments/production.rb和development.rb设置了smtp设置，我还在`config / initializers / setup_mail.rb中添加了设置
config.action_mailer.default_url_options = { :host => 'ipaddress' } config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { :address => 'smtp.gmail.com', :port => 587, :domain => 'gmail.com', :user_name => 'EMAIL_ADDRESS@gmail.com', :password => 'pass', :authentication => :plain, :enable_starttls_auto => true, :openssl_verify_mode => 'none' }
配置/初始化/为setup_mail.rb
ActionMailer::Base.smtp_settings = { :address => 'smtp.gmail.com', :port => 587, :domain => 'gmail.com', :user_name => 'EMAIL_ADDRESS@gmail.com', :password => 'pass', :authentication => :plain, :enable_starttls_auto => true, :openssl_verify_mode => 'none' } ActionMailer::Base.default_url_options[:host] = "ipaddress"
我收到错误Connection refused - connect(2)
虽然我在localhost中使用以下配置工作，但我没有收到任何错误，并且邮件已经发送。
config / initializers / setup_mail.rb（localhost）
ActionMailer::Base.smtp_settings = { :address => 'smtp.gmail.com', :port => 587, :domain => 'localhost', :user_name => 'EMAIL_ADDRESS@gmail.com', :password => 'pass', :authentication => 'plain', :enable_starttls_auto => true } ActionMailer::Base.default_url_options[:host] = "localhost:3000"
在控制台中运行时，错误显示如下

安装postfix ，错误在控制台模式下消失，邮件从控制台发送，但在图形模式下（在浏览器中）我收到错误Connection refused - connect(2) 。
怎么了，
提前致谢。
我发现您在两台服务器上都尝试过相同的设置，但仅在您的生产/非本地主机环境中遇到问题。
这指出了环境本身的网络配置问题。
在与应用程序相同的服务器上的命令行中，尝试以下命令
telnet smtp.gmail.com 587
您应该看到类似以下的内容
telnet smtp.gmail.com 587 Trying 173.194.79.108... Connected to gmail-smtp-msa.l.google.com. Escape character is '^]'. 220 mx.google.com ESMTP dd5sm276863pbc.85 - gsmtp
如果您没有看到这一点，您很可能会收到连接错误。 这意味着您的计算机无法访问gmail服务器。 可能的问题是a）一般的出站网络连接，b）防火墙专门阻止所有出站连接c）防火墙阻止/允许连接到特定端口或主机
如果这不起作用，也请尝试使用以下端口代替587
telnet smtp.gmail.com 465 telnet smtp.gmail.com 25
如果其中一个更成功，请更改您的邮件服务器设置以进行相应的使用。
编辑：我们在使用Gmail和Gmail以及我们的自定义域时遇到了很多麻烦。 有一点可以帮助您从配置文件中删除：域行，尝试没有它。
作为参考，这是我使用Gmail托管的自定义域生成的Gmail配置：
config.action_mailer.default_url_options = { :host => "my.website.com" } config.action_mailer.delivery_method = :smtp config.action_mailer.smtp_settings = { address: 'smtp.gmail.com', port: 587, domain: 'website.com', user_name: 'user@website.com', password: 'password', authentication: 'plain', enable_starttls_auto: true }
此外，如果您的Gmail帐户启用了双因素身份validation，则可能需要将其禁用并再次尝试此操作，以确认其不会使问题复杂化。
您将域名作为localhost。 该域名应为gmail.com。 请将您的config / initializers / setup_mail.rb更改为
ActionMailer::Base.smtp_settings = { :address => 'smtp.gmail.com', :port => 587, :domain => 'gmail.com', :user_name => 'EMAIL_ADDRESS@gmail.com', :password => 'pass', :authentication => 'plain', :enable_starttls_auto => true }
并在生产.rb。 您无需配置电子邮件地址。 以下几行就足够了。
config.action_mailer.default_url_options = { :host => 'app_url' } config.action_mailer.delivery_method = :smtp
