Rails Net::OpenTimeout Mailer Namecheap Heroku 無法發送郵件 500 錯誤

Question

>我试图通过namecheap域名发送重置密码的电子邮件。我已经审查了StackOverflow中提供的所有解决方案，但无法获得可行的解决方案。如果我在下面缺少任何详细信息，请告诉我。My Rails 应用程序只是一个 API。

它通过gmail连接/smtp工作，当我将其切换到namecheap/privateemail smtp时，它工作了一次。在本地工作后，我将代码上传到 heroku，这就是它开始失败的时候。

# config/environments/development.rb
config.action_mailer.delivery_method = :sendmail
config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.default_options = {from: '[e-mail]'}
config.action_mailer.default_url_options = { :host => '587'}
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
address:              'mail.privatemail.com',
port:                 587,
domain:               'domainname.com',
user_name:            ENV['EMAIL'],
password:             ENV['EMAIL_PW'],
authentication:       :plain,
enable_starttls_auto: true,
openssl_verify_mode:  'none',
ssl:                  true
}

生产：

config.cache_classes = true
  config.action_mailer.delivery_method = :sendmail
  config.action_mailer.perform_deliveries = true
  config.action_mailer.raise_delivery_errors = true
  config.action_mailer.default_options = {from: '[e-mail]'}
  config.action_mailer.delivery_method = :smtp
  config.action_mailer.smtp_settings = {
  address:              'mail.privatemail.com',
  port:                 587,
  domain:               'domainname.com',
  user_name:            ENV['EMAIL'],
  password:             ENV['EMAIL_PW'],
  authentication:       :plain,
  enable_starttls_auto: true,
  openssl_verify_mode:  'none'
  }

通告程序邮件程序类

class NotifierMailer < ApplicationMailer
  default_url_options[:host] = ENV['BACKEND_URL']
  default from: '[e-mail]'

  def create
    admin = Admin.find_by(email: params[:email])
    admin.generate_password_reset_token!
    Notifier.password_reset(admin).deliver
  end
  def password_reset(admin)
    @admin = admin
    @url = "#{ENV['BACKEND_URL']}/password/reset?token=#{@admin.reset_password_token}&email=#{@admin.email}"
    mail(to: "#{@admin.first_name} #{@admin.last_name} <#{@admin.email}>",
         subject: "Ion Portal - Password Reset")

Answer 1

这些设置对我有用。 事实证明，我也离开了MailCatcher的设置，这是我最初的问题。 还要仔细检查域设置和服务器地址是否匹配，这在开发中意味着将域设置为"localhost：3000"。 祝你好运！

config.action_mailer.perform_deliveries = true
config.action_mailer.raise_delivery_errors = true
config.action_mailer.delivery_method = :smtp
config.action_mailer.smtp_settings = {
:address              => 'mail.privateemail.com',
:port                 => 587,
:domain               => 'localhost:3000',
:user_name            => '[e-mail]',
:password             => 'xxxxxxxxxxxxxxx',
:authentication       => :plain,
:enable_starttls_auto => true,
}

Answer 2

经过 24 小时的反复试验，我不得不删除几行代码才能使其工作。

 config.action_mailer.smtp_settings = {
# For Gmail
      # :address              => "smtp.gmail.com",
      # :port                 => "587",
      # :domain               => "gmail.com",
      # :user_name            => "[e-mail]",
      # :password             => "pasword!",
      # :authentication       => "plain",
      # :enable_starttls_auto => true
# For Namecheap
      :enable_starttls_auto => true,  #this is the important stuff!
      :address        => 'smtp.privateemail.com',
      :port           => 587,
      :domain         => 'privateemail.com',
      :authentication => :plain,
      :user_name      => '[e-mail]',
      :password       => 'password!'
    }
I removed the following: 
    enable_starttls_auto: true,
      openss
    l_verify_mode:  'none'
